My 3D printer had a failure in the bracket for a pulley.

My 3D printer had a failure in the bracket for a pulley. My first thought was that I could just 3D print another but then my brain slowly realized that the 3D printer didn’t work anymore. The original part was made from 8mm plexiglass and I checked my sheets and found that I had 2mm thick expensive and very tough plexiglass so I decided to use it. This stuff is very strong but doesn’t shatter. To cut it into 300x200mm sheets I have to score it deep with a razor and bend it at a pretty steep angle. It behaves like a really tough Kydex.

Anyway, after about half an hour of measuring I printed out 8 pieces and glued them togeter, 4 at a time. I used CA glue and clamped them for a few minutes and I’m very happy with the results. I guess now it’s time for the 3D printer to make something for the laser cutter to return the favor. Maybe a cool knob or frame for the power meter.

Plexiglass that is tough and doesn’t shatter ? That sounds like polycarbonate not acrylic (Plexiglass is a brand-name for acrylic).

@Henner_Zeller It could be. The label was thrown away after I bought it but it was pretty expensive compared to the cheapest stuff I have that’s brittle. I bought it for making leatherworking templates. Mostly wallet designs.

The ability to repair machines using other machines is probably one of my favorite things about having a CNC hobby shop. Great work!

@Madyn3D_CNC_LLC I agree. I was upset that the part broke until I realized it was an opportunity to make something I needed. I’m actually glad I got the chance to do it.
