Simple housing case with Snap-fit for KY-040 or similar Rotary Encoder. It has a hole in a cover for easy mounting under a desk or anywhere else with a screw. Easy access to the 5-pin DuPont connector.

I had 2 slightly different KY-040 models with different space between mounting holes:
- 11.5mm
- 14.5mm

Box Options
There are 2 height options for a box:
- 15mm - default
- 17mm - more clearance between the KY-040 and Cover (To make sure the screw doesn't touch the rotary encoder board)
And 6 cover options:
- No screw

- M4
- M5
- M6
