I wanted a mount for an IKEA Dioder that would position the lights on the front side, but attach on/around the back side of the top of the frame (as to not impede the extruder). Threw this remix of two designs together in tinkercad which should be exactly what I'm looking for.
Updated with taller variant (added 50mm of height) in order to ensure clearance of extruder. The original cleared the extruder, but not the filament sticking out of the top when at max Z height. The tall version allows for full Y axis range of motion when at max Z. One note regarding the taller version, I had to position my filament arm all the way to the left (up against the dioder arm to be able to load/unload wider spools (prusa filament spools).

I printed in the Prusa orange PETG so it would match my printer, but this should work fine with any PLA, ABS, or PET filament.
