This is a retro-styled 3D-printed case for the Reviung 34 Split, inspired by vintage Cherry and IBM keyboards. It assembles using magnets and Geon x Nuxros Keysnap.

he top case has relief cuts for the RJ45 ports and cables, however I designed this around very slim, low-profile Monoprice Micro SlimRun series cables and recommend either buying those or verifying that your cables will fit, especially if they have strain reliefs.

The top and bottom case parts attach magnetically. It's not easy to route or detach the USB and RJ45 cables with the case fully assembled, so the magnets make it easy to pop the top off and unplug or plug in cables.

Note

Geon Keysnap

Silicone or FKM

I used 50A, which is the softest, so anything harder should also work well

Magnets

5 mm OD, 3 mm tall

16

To secure top and bottom halves

Feet/bumpons

8mm diameter, 4mm tall

The holes for these are 2.5mm deep, so you'll want something 3mm height or taller.

Assembly

The following assumes you are disassembling an already built Rev 34 Split.

  1. Unplug any cables attached to your keyboard. Remove the bottom of the sandwich assembly on each half of your Reviung 34 Split. I did this by removing the screws that secure it to the plate, so the bottom comes off with all standoffs, as well. I did not test fitment with standoffs left inside the rest of the assembly.

  2. Once the bottoms are removed, unscrew the MCU cover and remove the standoffs for it as well.

  3. Place the keysnaps around the edges of the PCB. I used 6 per half, and placed them so that the board assembly is as evenly supported as possible (see photos for placement)

  4. Push the board assembly with keysnaps installed into the bottom case for each half. This is similar to assembling an board that uses gummy o-ring mount, and shouldn't require much force.

  5. Press magnets into the magnet holes on the bottom and top case parts, being mindful of polarity so the two halves will attract, rather than repel. I tried to design them for a snug press fit, but a dab of superglue may be necessary.

  6. Plug in all of your cables at this point. It will be more difficult to attach or remove cables with the top case assembled.

  7. Attach each top case to the bottoms.
