I recently moved to a new city into a shared apartment. Everything is clean, but small things were broken and no one really repairs stuff. My first thought: I can 3D print that. I bought a printer and started with this shower drain cover. My roommates had never seen 3D printing before, so we recreated the original €20 replacement part together in CAD, printed it, installed it — perfect fit. The original part went back 😄 I love fixing everyday problems with 3D printing. What did you repair last?
