I took some inspiration from https://www.thingiverse.com/thing:1134134
I don't consider this a remix because I ultimately started from scratch in Fusion 360. The Fusion 360 files are attached for anyone wanting to remix from that. It's my first time fiddling with it, so don't judge me too harshly ;)

This one uses a switch with a larger angle, so the switch itself is further down than the one above. Some of the switches I have worked right out of the box while others required a slight bend to get it to activate correctly.

I printed this with a dual extruder printer, but that is not required. For single extrusion printers, just ignore the arrow file. Then the parts will print with an arrow indentation.

These are the switches I bought from Amazon:

EDIT 5/9/2021:
I added arrow models in the correct position for each side, and I moved the position of the switch up by about 0.6 mm since it seemed that worked better for most of the switches I have.
