[UPDATE 10th June 2022]

I noticed error in my design. Design didn't have enough room for right side controller and TRRS jack since they are slightly different position due holes in PCB. I changed the design to have slightly more room around the controller area. I have updated new STL files and removed old ones. 

This is 3D printable case for Kimiko split keyboard. It has three parts: 

• Top cover with key slots. It's 1.5mm thick and locks to Kailh switches.
• Bottom cover, there is 2mm clearance for bottom of the PCB. This should make Kailh hotswap sockets sit against bottom
• Full cover for controller, reset switch and TRRS jack

The design is based on original Kimiko cad files from GitHub.

Top cover has threaded M3 holes modeled in, attaching bottom and top cover you will need 7 standard M3x8mm countersunk screws and two more to attach controller cover. 

I did not check clearance for LEDs or OLED screen options. Atleast top cover won't fit with OLED.
