[IC] +84 Classic TKL [Krush Series] Designed by Nuxroskb

[nuxroskb]

Hello everyone,
Here’s the next product in my Krush series: [+84].

If Krush is the “friend you like,” then [+84] is the “call” to her/him.
On top of that, [+84] has another meaning: “80 for everyone,” and it represents the number of keys on a TKL keyboard

My goal with this product is to capture a classic, simple elegance clean and refined, without unnecessary details or excessive accessories. I want to deliver a satisfying typing experience with rich, pleasing sound, something people can enjoy using every day. This is a product not just to look at, but to truly experience.

Following the success of the Krush65, this time I want to focus even more on enhancing typing feel and sound quality. Designing a TKL keyboard that delivers an exceptional typing experience and satisfying acoustics is truly a challenge. I have experimented with dozens of parameters and configurations to achieve the best possible final product. As a result, this new model offers a typing feel and sound quality that surpasses the Krush65 by a significant margin.

Q&A

Q: Can it be used with the Venom TKL F12 PCB?
A: Yes. I designed the case based on the VENOM PCB, so it will be 100% compatible.

Q: Can it be used with other PCBs?
A: Yes. It can be used with Hiney’s PCB.

Q: Will you upload the plate file?
A: Yes. I will upload the plate file after the project is completed.

Q: Will you sell the PC top case or bottom case separately?
A: Sorry, I’m afraid not.

Q: When purchasing an extra PCB, will it include the daughterboard?
A: Yes, it will include the daughterboard.

Q: Can we use Keysnap?
A: Yes. It can be used, but only with the Venom TKL PCB and the Solder PCB

Appreciate you providing IRL photos of some of the colors. That Red is really vibrant. Reminds me of GMK Red Devils. GLWIC

[DirtyGingy]

I've been waiting for this one. I didn't see the top mount option at first and was worried, but I'm glad it's stithere

[rfcclub]

Finally a TKL with a very very reasonable price especially for patina copper weight. For me it's a must-buy. GLWIC !

With Split Left-Shift being unable to be done on the Krush65 due to the plates being made incorrectly. Has this been addressed in this project?

Plus one to this, while I absolutely love my Krush65 - having to file down the plate because it seemingly wasn't tested with all supported layouts was a huge detractor. Please can you confirm you're actively testing for such issues on this project, across the board (in the past year I've seen plate issues, clearance issues, and firmware issues with non-ANSI layouts) - I only want to support projects where the designers own their past mistakes and learn from them going forward.

Of course, don’t worry. I’ve already learned from my previous Sebas project. With +84, everything will be perfect. Krush65 was my first project, so there were some mistakes, and I’ve learned from them. That’s why +84 will be a much better product than Krush65 in terms of sound, typing feel, and other small details.

Additionally, because I want to focus fully on achieving the best sound, I removed support for multiple layouts. Having too many cutouts on the PCB can compromise the sound, and I tested many versions before. For example, Krush65 supported multiple layouts, which caused the sockets to rotate up and down, negatively affecting the sound. I learned a lot from Krush65.

Thank you, IC completed.

such a good price and design, GLWIC!

[FOURRINGS]

This looks very clean

[VXQN]

Nice colours. Can we have some larger images so we can see the details? As they are it's quite hard to really get a sense of the bezel proportions.

Yes Ill update it on my Discord

Definitely, it has to be top-mount hehe

such a good price and design, GLWIC!

Thank you so much !!

Hehe Let's go ! 

[Randomlosername]

lookin fire bro!

[Dingo_Seven]

Looking good, hopefully you have been well, but I wanted to ask if you would consider making the USB-C port cutout a bit larger for either this project or future projects?

This allows folks like me to use larger connectors that are present on braided or artisan cables.

[NihonCK]

should probably update the IC about how the front logo is now a sticker

[DirtyGingy]

As much as I love this project, I strongly preferred the top case with the design on it.

Due to IC's feedback (and to accommodate more people), we are switching the +84 logo from the actual engrave on the board to a metal sticker (similar to the Geon logo) so people can decide whether they want to have the logo on or not.

This was the correct choice.

[Kool-Keys]

A bit sad to see the case engraving go, but still excited for this.  I loved the 65.  Price is crazy good as well. 

[VXQN]

You didn't actually put any better photos here or on Discord. Can we see some?

We are in the process of sending out the boards to content creators so expect proper contents to come in the coming weeks.

It is still there, just in a different form now to accommodate more enthusiasts.

Will Racing Green match BRG Pantone 5535C so that it actually matches GMK British Racing Green?

Let me share more details with you about the +84 project.
Over the past few days, I’ve been cutting and testing many different plate variations to find the best cut out design for optimal sound performance.

1. The first issue

The stock black plate that came with the keyboard was laser-cut by KZW instead of being CNC-milled.
Because laser cutting generates heat, the switch holes were slightly misaligned, causing the plate to warp during assembly.
As a result, when installed, it produced unwanted reverb due to these small inaccuracies.

2. The second test

I then cut a new CNC plate myself – the raw-colored one next to the black version.
I experimented with cutouts around the screw positions, similar to Jane or Merisi boards.
However, this led to more vibration.
I also opened up the spacebar cutout for better acoustics, but it ended up being too wide, causing sound leakage and uneven tone.
I even made the stab area more open to make it easier for users to remove stabilizers, but this unintentionally made the spacebar rattle more.

3. The third version

For the third one, I kept the same design as the black plate, but switched from laser to CNC cutting.
The sound was much cleaner, though the spacebar tone was still not fully balanced.

4.The final version

The version I’m currently assembling is the final revision, made with the help of my close friend @Keytamin.
He gave me great advice and helped me refine the spacebar cut out, resulting in the best sound I’ve achieved so far.

In this final version, I also added mounting holes for those who plan to use Venom TKL HE PCB.
I’ve already sent the files for CNC production of the PCBSnap plates based on this final top-mount design, and I’ll continue to update everyone once I receive them.

Hello
This is a sound test I just did for +84 with the final plate cutout, using a Pour Topmount mounting, and there is almost no hollow sound at all (Actually I can still hear a tiny bit of the characteristic metal sound of topmount near the keys close to the mounting points, but it’s very minimal).

I’m testing on a hotswap PCB and haven’t really fine-tuned the spacebar stabilizers yet.
In the video, at the last few seconds, you’ll see the issue with the MX Black that I mentioned in "⁠working-with-nuxros” yesterday you’ll need to adjust the spacing a bit to get an even and better sound.

[nuxroskb]

10/18/2025

Today I worked together with @Keytamin, who has been helping me a lot with the plate and assembly. He just finished building the top mount with MX Black without using my metal accessory kit.
The result was great! There wasn’t even the slightest hollow sound with the MX Black hehe.
That means I’m now ready to prepare for the GB !!!

Nice. Do you have this type of sample for burgundy and green?
