I took some inspiration from: https://www.thingiverse.com/thing:4818473 I don't consider this a remix because I used no part of the original files. This design also attempts to instead use the snap-in feature of the switch itself. It is not designed to be very serviceable as it's a pain to remove the bottom plate and the switch itself.

The stress relief is designed for a 4 mm diameter cable. Just enough space is provided inside for such large cable. I personally used hot melt to isolate the switch wires and keep the cables in place, but I am not kidding myself into thinking that this will be very durable. There wasn't enough room to make knots at either end.

I provided the FreeCAD files as well for anyone wanting to remix.

EDIT 4/25/2021 I updated the ridge in the top piece in order to reduce the amount of supports needed to print. Now it can be printed upside down with support settings for "only touching build plate".
