I would have hoped for a bit more bezel but I am aware this probably puts me in the minority...but I am definitely in. However something just struck me.

Please consider offering an add on folded palm rest, just a simple wedge shaped profile that would go along nicely with the case. Should be easy to manufacture and not too expensive.

Too bad the material used is not ferrous as it would be possible to use magnets to attach the palm rest to the case. Maybe still a possibility somehow, hmmm...

I LIKE BIG Bezels...

yeah, me too :)

I actually had shown such a design back in the IC for the SKB1. the top part had the rest included. I might experiment with it again, not sure atm. see (oh, already three years old now):

It definitely is ferrous. The whole point of SKB2 is that it's made of ferrous steel. Only the stainless version might be non-ferrous, and even that is unlikely since I'm guessing he's using 18-8 stainless which is mildly magnetic. Only something like 316 would be completely non-magnetic.

the stainless steel version will be made of V2A.

@PlastikSchnittstelle Are the plates going to support Maarten's switch top openers?

sorry, I don't like the cutouts to allow for switch top removal. I want the switch to sit tight. you'll need to get your switches right before you build.

During the SKB1 GB I made custom plate DXF for everyone who asked for it. Quite a lot got their own plate this way. I'm planning to offer my help the same way again. Maybe this time a custom plate service that not only gets you the file but a physical plate instead, not sure about that yet.

That'd make my life way easier, it's not that much of a hassle to go to Laserboost and do it that way but regardless.

Thanks, I'm not feeling so lonely any more.  :D

An add-on palm rest for the existing design that would get you close to the one depicted above would be most welcome. Not a deal breaker by any means, I guess it wouldn't be too hard to get one done myself, but definitely easier to get it a s a bundle....if there is interest of course.

This looks awesome, although I can see a few limitations right off:
  • If the feet at the front are at the edge of the palm rest, it would be very difficult to angle the board, i.e. the feet at the back would have to be way bigger to allow the same angles
  • If the feet at the front are where they usually would be (without the palm rest), the palm rest would stick out in the lowest angle setting and would probably tilt the keyboard when you rest your hands on it (unless of course there are feet there too, which would mean one extra pair of feet for each angle setting)

Maybe if the palm rest is semi-rigidly attached in some way that allows changing the angle...

The front row height is already very low so I personally don't see the need for a wrist rest. The design is already set and either adding a separate wrist rest or integrating it - it is both something that should be considered from the beginning. Too late to add it now. I may explore this in the future. Not for this run, already a  lot of different versions and sizes.

 :(

Have you seen the 65% PCB from Maarten? It does support exactly that layout. Tsangan bottom row for 65%. For this GB he'll design a new 65% PCB, same layouts like his Ta-65 PCB, it will get USB-C and will be called "Eon67". Mentioned here.

Here you can see the supported layouts:

How will the plates accomodate that?
Will the plate support all layouts possible on the pcb or will there be fixed layouts to choose from (for example ISO plate, ANSI plate, etc.)?

The usual way, like it's done with most other custom cases.
Unified plate.

Here you can see two different prototypes, the lower one is newer and not jet surface treated:

An updated design is already ordered, it will look like this:

Some desk pictures

Sorry, still haven't had time to do good pictures of the current prototypes. Since the 3rd prototype batch will be ready in about two weeks from now, I'll wait until I get it and then get pictures made from all. Will need to get some more keycap sets until then.

Until then, I managed to get just enough light on my desk to make at least a few ok shots. Honestly, I was unsure if I should post them because the light is obviously still bad but you should be able to get an idea of how it might look on your desk:



Btw, I only use R5 bottom row. That RGB-MOD is from a GB quite a while ago that included 1.5U R5. Another one that will also include 1.25U R5 is currently in IC, over here.
I'm very happy with the deep black zink surface treatment of the plates.
60% is RAL9001, 65% is RAL9002. Next prototypes will include RAL1013.

RAL colors and glossy coating

I've been to the company that is doing the powder coating. We've discussed the glossy coating. I won't go into detail but basically a perfectly even surface with glossy is not simple and the outcome depends on various factors.
Earlier here I had already concluded that the interest for Finstruktur is much higher anyway, which is why it will be the only option.

Looks like these will be the available RAL options (all Feinstruktur):
- Classic Beige: RAL9001 or RAL9002 or RAL1013 (vote will decide)
- Gray / Dolch: RAL7039
- Black: RAL9005
- Yellow: RAL1023 (waiting for the next protos to confirm this)

...and of course the nickel coated, bead blasted, stainless steel version

Will voting for beige be excluding (only one color may be chosen) or we will be able prioritize the colors (most desired option, second best option and least preferred option)?

Can you speak to how these the different plate designs felt? Really curious what the results were and why you chose to make the changes to the cutout design you did. I'm also interested in snagging a TKL.

Thanks for the link I apologize for missing it I read the thread but must have missed that one. Interesting to read. I guess the relief cuts make less of a difference on these steel plates since they're so much stiffer by themselves already that even with there being only a little piece connecting the inner and outer regions of the plate it didn't significantly impact it.

Is structural integrity a bit concern? I had thought for steel it was strong enough to not really have to worry about it.

I guess the relief cuts make less of a difference on these steel plates since they're so much stiffer by themselves already that even with there being only a little piece connecting the inner and outer regions of the plate it didn't significantly impact it.

Look, here are two brass plates I have had done:

234817-0

Yes, I also have had brass plates made, just to get to know the difference. Same relief cuts. Although I have not jet made a complete build with it, I can tell that there is almost no noticeable different compared to the same plate in steel (I don't have it with the superlong and winded cut, that I can't compare atm). Brass feeling so much better is a totally overblown statement that many take much too serious. I bet that in a blind test of two boards that are built identical (same case, switches, caps) with the only difference being one has a brass the other one a steel plate, most would not be able to tell them apart. Some who make a lot of builds may be able to.

IMO the difference between brass and steel is negligible. Though to be fair and like I have mentioned, I haven't done a complete build with the brass plate jet, so there is still a possibility my opinion on this might shift a bit, but I doubt it would be much.

Apart from feel, what I personally don't like about having a brass plate in my keyboard is the fact that the golden shiny look makes me think of a rapper showing me his gold teeth. That gold bling bling looks terrible to me. I know, it is possible to bead blast the brass plate so it will loose the reflectivity and then further give it a black coating. But that is quite pricy and the small difference in feel would not justify that imo, not for a custom that aims to be more affordable. For a very high end custom, yes, sure, every bit of improvement, even if it is just small, is justified.

Is structural integrity a bit concern?

NO, it is not a concern. Not at all. If it would be, I would make changes. This thing is brutal.
Just look a chart that compares the density or weight of metals. Compare alu to steel. Oh, and when you look at that chart, please also compare steel to brass ;)

Before the GB starts, will send the protos to reviewers who can give their opinion about the board, so you don't need to rely on my word.

I totally appreciate your questions, they are totally reasonable to ask and should be ask. Thanks.

yes, there is nothing left to be changed now. just if the pcb for the 75% looks to be ready in time I might have to do a quick proto of that size as well. other than that I'm making preparations for the gb. but these preparations take some time as well.

Personally agree on the brass plate aesthetic. I know some like it but I also dislike it. Have it on a build Iím doing at the minute and feel it cheapens the look.

I guess the relief cuts make less of a difference on these steel plates since they're so much stiffer by themselves already that even with there being only a little piece connecting the inner and outer regions of the plate it didn't significantly impact it.

Look, here are two brass plates I have had done:

(Attachment Link)

Yes, I also have had brass plates made, just to get to know the difference. Same relief cuts. Although I have not jet made a complete build with it, I can tell that there is almost no noticeable different compared to the same plate in steel (I don't have it with the superlong and winded cut, that I can't compare atm). Brass feeling so much better is a totally overblown statement that many take much too serious. I bet that in a blind test of two boards that are built identical (same case, switches, caps) with the only difference being one has a brass the other one a steel plate, most would not be able to tell them apart. Some who make a lot of builds may be able to.

IMO the difference between brass and steel is negligible. Though to be fair and like I have mentioned, I haven't done a complete build with the brass plate jet, so there is still a possibility my opinion on this might shift a bit, but I doubt it would be much.

Apart from feel, what I personally don't like about having a brass plate in my keyboard is the fact that the golden shiny look makes me think of a rapper showing me his gold teeth. That gold bling bling looks terrible to me. I know, it is possible to bead blast the brass plate so it will loose the reflectivity and then further give it a black coating. But that is quite pricy and the small difference in feel would not justify that imo, not for a custom that aims to be more affordable. For a very high end custom, yes, sure, every bit of improvement, even if it is just small, is justified.

Is structural integrity a bit concern?

NO, it is not a concern. Not at all. If it would be, I would make changes. This thing is brutal.
Just look a chart that compares the density or weight of metals. Compare alu to steel. Oh, and when you look at that chart, please also compare steel to brass ;)

Before the GB starts, will send the protos to reviewers who can give their opinion about the board, so you don't need to rely on my word.

I totally appreciate your questions, they are totally reasonable to ask and should be ask. Thanks.

Thanks so much for getting into this with me I am not trying to question or doubt your work just understand for myself!

Have you done that kind of blind testing for aluminum vs brass/steel? The other case that I saw using this similar style of relief cuts on the plate (the community seems to refer to it as leaf spring) was the thermal. That board used aluminum in its plates. I don't know if that decision was for the reasons you described but I wouldn't be surprised. The stiffer the base material the less important having the bridge that connects the inner/outer pieces of the plate be thin is. Hope that makes sense!

Alu, no haven't tried one for this project. I have ever only used an alu plate once. No side by side comparison. It is really difficult to quantify the difference if you don't compare them in the same kind of builds side by side, I think. In theory (comparing density of the materials) alu should let you feel more of a difference compared to brass/steel. Apart from the plate feeling, I can compare the SKB1 (which was made of alu) against the SKB2 (which is made of steel but also slightly different construction). The difference is absolutely huge, it is something completely different.

The other case that I saw using this similar style of relief cuts on the plate (the community seems to refer to it as leaf spring) was the thermal. That board used aluminum in its plates. I don't know if that decision was for the reasons you described but I wouldn't be surprised. The stiffer the base material the less important having the bridge that connects the inner/outer pieces of the plate be thin is. Hope that makes sense!

Yes, I've seen the term "leaf spring" being used for this kind of cut. I googled leaf spring but what I find is something different. The way I see it, this term does not apply here. How do I think would this cut behave in alu? Hard to say, I think it would be more fragile and break easily, but I can't really say.
Yes, the relation of stiffness & thickness makes sense to me. I just think that what is correct in theory does have a much lesser impact in reality than one might expect. Also keep in mind that we are not typing on just the plate itself. After the plate is sandwiched between switches and pcb, that entire thing becomes something very compact and the effect of the plate material is less noticeable probably for that reason as well.

Let me clarify that I don't think brass is generally something ugly to me. Seeing a nicely treated brass plate by itself or as weight in a milled alu bottom piece is always absolutely astonishing to watch, it's hard not to like that. Just the shiny brass reflecting between plastic keycaps is what does not fit for me. I prefer the classic beige stuff most of the time, this just isn't a good match with the look of brass. However there are keycap sets that do indeed look good with a brass plate peeking through. So, in the right combination, even I would appreciate a brass plate :)

Can we have a typing video? I want to know how it sounds like :D

Would you be able to use something like a ISO HS60 v3 with this case/plate combo?

This project is fantastic, but I'm not sure that I'll join it for a simple reason, I hate bezels.

Right now I'm using a bezel-less gmmk keyboard, and it's such a joy to use when compared to a keyboard with a bezel, like the g80-3000. With that keyboard, my left-palm constantly touches the border, and when you rest your hands that border becomes really annoying. I wonder if the skb2 has the same problem of a g80. Judging by the dimensions it has. Correct me if I'm wrong! thanks

I think bezels are nice tho! If resting off the bezels are tough then we can always make them bigger and nicer to rest on! :)

You're describing pretty unhealthy typing posture. Your palm shouldn't really be below the height of the keys when typing. Instead of searching for keyboards that accomodate your posture, you could try changing your posture a bit. Ideally there's a relatively straight line from your arm to your hand. In addition to more healthy wrists, you also get the advantage of being able to use big bezel bad boy boards like this one.
