Tiwaz - Split keyboard with modular joysticks

Tiwaz is a split keyboard with multiple joystick options. Each half can be used independently as a one-handed gaming keyboard or macro pad. QMK, VIA, VIAL support lets you remap keys directly in the browser without reflashing. More information on my GitHub.

The case models are left hand side. For the right hand side simply mirror in your slicer. Additionally, it is designed to be CNC machined (no sharp internal corners).

If you decide to use the PSP3000 Joystick, get one with a thumb cap.


Parts to Print

Part

Notes

Case Bottom

Use 9x 16 mm long M2.5 screws with flat countersunk head

Case Top

Two variants: insert (for heat-set inserts) or tap (thread directly, e.g. CNC aluminium)

Plate

Can also be CNC or laser cut

Joystick Insert

Match to your joystick: RKJX21224001 or PSP3000 / RKJXU1210006

Thumb Cap

Only needed with the RKJX21224001 joystick

Button

6 pieces, transparent / clear material for backlighting


Parts to Cut

  • Laser cutter or cutting machine recommended

  • Gasket top and bottom

  • Gasket large and small, 6 of each

These parts are press fit. You probably want to scale it up a bit. I did 0.5mm on X-Y. Or  use a few drops of super glue ...


Print Settings

Since the case is designed to be CNC cut, tolerances are tight. X-Y compensation may allow beter fit for screws or heat-set inserts, but throw off others like the joystick inserts. You might need to experiment with other settings or scaling. The only issue I had on my Voron 2.4 were boogers near the seam of the transparent PETG for the buttons.

Printing in FDM, I used hole compensation of 0.1 mm.
