Shure SM58 Mic Battery Cup Replacement

thingiverse

The battery covers or cups on the wireless Shure SM58 easily crack and eventually break around the threads if you twist the cap on a little too tight. This started as a remix of pmcpajadan's battery cover but I decided to re-implement it in JSCAD to make customization easier. Unlike most SM58 mic cups, this has a flat bottom for printing without support. The tolerance is pretty tight so I included the OpenJSCAD file just in case it needs to be tweaked. To make sure I had the thread tolerances right, It worked for me to invert the print with threads down and interrupt if after the nut portion finished printing. Then I could test that piece on my mic. The final print needs to be bottom down (aka threads at the top) unless your printer is awesome at bridging!
