will probably need trial and error to set hinge size - what is an interference fit on an Ender 3 is a loose running (aka hinge-falls-out) fit on a Prusa i3 mk.3s

Modification of Davross's XBox adaptive controller low cost/force buttons:

1. Enlarged hinge to take 3 mm spring pin
2. Enlarged hole for button so that a wider variety of 12 mm buttons would fit
3. Shave a little off the back of the switch so that high speed FFF printers can still produce overhang and the switch will work
4. Printed on its side for stronger hinges.

Note that printing both parts on their sides - while resulting in stronger hinges - makes for amuch longer print time.

If you wish to modify the design further in OpenSCAD, you'll need the btn_base.stl and btn_top.stl. An archive copy of the files is here: https://web.archive.org/web/20190404034437/https://cdn.thingiverse.com/zipfiles/1f/42/25/ac/92/XBox_adaptive_controller_low_cost_force_buttons.zip

Notes are included to help you should you wish to try a shorter button.
