I remixed the case from the original 4x4 macro keyboard linked below and modified the dimensions in prusaslicer. This is pressure fit, so it just snaps in.

size
108.3
56.52
12.95

scale:
101.37
74.58
100

I printed this in 0.25mm DRAFT mode in prusaslicer with the following modifications:

layer height: 0.25mm

nozzle size: 0.4

infill: 0

vertical shells: 3
