for more details.

Removing the switch from its original enclosure can be destructive, so a new enclosure is needed. I modified a small bowl (shaving), and added a slot and groove to allow a usb lead to be inserted into the base.

The fit on my printer is a snug interference fit, and no glue was needed to hold the switch in place, and there's a series of small internal indentations (from original shaving lid use) where the original switch clips can just fit in.

Notes:

I printed this at high resolution for a better finish, but it's not really critical.

A good fit on my printer, but tolerances may vary between machines, and you may need to sand, glue, or enlarge/shrink the print as required.
