Reel for divers for the buoy when diving (75mm diameter, 24mm wide)
A friend asked me for a replacement reel as his broke while entering the water.
I printed it with Prusa PETg, 100% infill and glued it with expoy together. Because of the split design, no support, raft or brim is necessary.
It's more or less indestructible now for the purpose intended.
