Hey everyone.
Not sure if this is exactly the place to ask this question but I was wondering if anyone knows a good place to get rubber feet for a case. I own a TEX Case (Bronze) for the Poker 2, but the case itself is pretty flat. I would prefer these type of feet (http://prntscr.com/6g132o) or something close to that, but I'm not sure if those kind are stick on or screw on. Thanks for the help in advance!

Those are machined aluminum feet with little round rubber bump ons. You can get the machined feet from GON. I suggest looking for 3M Bump Ons.

These are the best, but more $$$

I would recommend these guys: http://www.bumperspecialties.com/products-ezp-2.html
I have bought lots of different shapes and sizes from them. My preference is clear.
Edit: for the record, I did weeks of research before going with these guys.

I agree with the above. These are great feet and are available in 1/2", 3/4", 1", and 1.25"; and I prefer 1/2" feet, but this is a matter of personal preference.

If you don't want the expense of the Sorbothane (Google for cool facts though) then I think Swill's suggestion is a great option too. Dude knows his stuff for sure.

If you are in the US, you can probably get cheaper ones off amazon than from my link, but I found it hard to find exactly what I was looking for. When the link they have basically every size and shape you could want, so if nothing else, use it as a guide for what size and shape you want when buying elsewhere.
Be sure to calculate the pitch of your keyboard given the size of the bumper and the location on the back of the keyboard you plan to put it. I ended up using smaller bumpers than I expected to use.
-
Also, if your bumpers are really big, fix them on with Velcro rather than adhesive. Then you can remove them to fit in a case, etc. This is also good for trying different sizes.

Thats pretty good advice. One other thing I would note is be very careful about how you place them. You need to make sure they are really level (lined up) so the keyboard sits really even and steady. I think the velcro would probably add a nice cushion for error as well. It is often the case with bumpers that the diecut around the bumper (off the sheet) is not perfectly centered and you have a little extra of the sheet on one side vs the other, so it can be a bit tricky to line them up nicely. I put 4 in a row on my 75% board and it felt pretty good. I got lucky and got it on the first try, but I clamped a ruler along the line I wanted them on when I applied them to help line them up.

I'm a sucker for a well-organized web site. Not only do they have just about everything in every imaginable flavor, it's easy to find. Their prices aren't always awesome but it's worth it.

Does anyone know dimensions off the top of their head on the stock 3M adhesive bumpers/feet that come with tex 60% cases? I'm checking out McMaster-Carr right now and I want to buy everything

This thread made me considering doing a kit with multiple sized rubber feet I put up an IC thread here -> https://geekhack.org/index.php?topic=69876.0

Possible stupid question: Has anyone ever tried using magnets as feet on an aluminum case? Something like this (http://www.kjmagnetics.com/proddetail.asp?prod=DEC) or this (http://www.kjmagnetics.com/proddetail.asp?prod=D84PC-BLK&cat=1)(pardon the random dimensions). Obviously the angle won't be perfect as the magnets are cylinders but I'm thinking a small rubber bumper on the bottom might be able to sort that out.
I have the tex 60% fat lip case without feet, but there is a small recess that a magnet might fit in to nicely. I can't imagine a strong magnet would cause any issues with the PCB. Could a magnet create any issues with the spring inside the switches themselves? I'd love if someone smarter than me has any input.

drooled at their homepage
I also enjoy custom sliding/non-sliding bumper additions to stuff, yet if the surface isn't extremely flat, the adhesives just give up, things turn pretty annoying

I did the same (weeks of research) and I concur that Bumper Specialities seems to be the best bet. It's what I use. Amazon sells them, too. Their stuff is of great quality. (USA! USA! USA!) To be specific, this is a good starting point:
http://www.amazon.com/gp/product/B008UFLK9W/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 (http://www.amazon.com/gp/product/B008UFLK9W/ref=oh_aui_search_detailpage?ie=UTF8&psc=1)
My only complaint is that the adhesive they use leaves sticky goo all over everything. Nothing is perfect.
The problem with Sorbothane (which is awesome in the right applications, also, USA! USA! USA!) is that Sorbothane is really for vibration or impact damping and not for anti-slip action (though it does that well). Due to this, their selection of bumpers that are less than 1/4" thick are quite limited.
I love them for big stuff like Hi-Fi equipment, motor and pump mounts, and shoe insoles, but for keyboards most of their stuff is the wrong size- way too thick, and their thin stuff is way too small, and you really don't want hemispherical squishy feet for keyboards as your keyboard will wobble (but not slide) all over the place if you put lateral loads on it. That's no fun at all, and feels really weird.
3M Bumpon is sufficiently nice, but not as nice as the Bumper Specialities stuff. That said, it will make you happy do if you can't get Bumper Specialities stuff for whatever reason.
