This is a 'Corne cherry keyboard' case.

There is a case of HI-Pro type in Thingiverse, but there isn't case of Lo-Pro type. So that, I designed a case of Lo-Pro type.

Thingverse has a case of Hi-Pro type, but there was no case of Lo-Pro type, so I created this 3D model.

You print this model, then remove the default bottom plate and screw. Finally, you assemble this case and PCB board.

If you want to customize this model, you edit the .step file.
