Comment on Assembled my first 3D printer

On the chance that it helps you at all, I broke the same part.

For some reason Prusa loves using those slim squarenuts that tend to bind up due to how few threads they have. Chances are the nut in the pully bound up and stripped out the plastic so now it’s just spinning with the bolt.

There’s a few community made models on printables that replace the nut with threaded inserts. The part should be printed in pc-cf however, and that’s frequently out of stock it seems.

Ah I see. I’m guessing I need a hardened nozzle since it’s CF. :/

  A hardened nozzle for sure.
  
  You got this repair, you built this thing remember? You are the master of your printer.

    Actually ended up printing the part with PETG. It worked and the issue is fixed (for now). Removing the broken part was a huge pain. I ended up using a drill and just drilling around where the nut is until I could fit tweezers onto the nut then I used the tweezers to keep the nut from moving and a screwdriver to loosen the nut until the part came out. All-in-all it was pretty time consuming and annoying. Hope I won’t have to do that again for a while.

    I think I’m just going to buy the part from Prusa.
    
    They appear to be out of stock for PC - CF
    
    PC releases harmful fumes and needs to be ventilated. I’m going to find a venting solution eventually but not now.
    
    The part is way cheaper than a spool of the filament, I can get a few in case they break. I know I can print a lot of parts with that same filament but I don’t really have an interest in printing with PC - CF.
