I needed a place to put a switch for the LED strip lighting I'm about to install on my printer, so I knocked this together in a few minutes in OpenSCAD. It bolts up to existing screw holes in the top of the frame (on the right, though if you set your slicer to flip or mirror the STL file on the X-axis, you could put it on the left).

I gave it a 1/4" hole for the toggle switch I'm using, though you could easily change size or shape, add more, etc.

(updated 21 Jun 18: added the two-hole panel with labels that I'm currently using.)

A8-0004.stl is a copy of the frame top panel from https://www.thingiverse.com/thing:2288314 and is included for reference. (Uncommenting the first few lines in mount.scad will make it show up in gray in the preview; this is how I lined up the mounting holes. Leave them commented out for the final render.)

Post-Printing

Clear the mounting holes with a 1/8" drill bit and the switch hole with a 1/4" drill bit if necessary (probably will be if you're printing at 0.2 mm).
