This is a keycap for the low profile Cherry MX1B-L2NA switch. It prints perfectly on a Prusa Mini with 0.15 mm layer height.

The keycap is easy to put on, doesn't fall off and is still easy to take off.

Created this basic keycap in tinkercad: tinkercad.com/things/eYS9n6hJxzm

You can download or change to your liking as I made the design public.

The macropad I designed this keycap for can be found over here…
