Simple shower door knob / handle for M8 screw / nut

thingiverse

Replacing a shower door knob that was originally made from metal but had been compromised by water and lime over time requires careful attention to detail. The original knobs are held together by a 30mm M8 threaded rod, which must be preserved in its entirety. To achieve this, you can either use the v2 STL file with a 40mm M8 screw or the v3 STL file with an inlay M8 nut that is no taller than 7mm.
