Y motor holder damaged during assembly
Hey all,
I have an issue where the washer wouldn't go properly into the y motor holder. Because of this, I tried to screw in a screw by itself into it, but when I tried to unscrew, it stripped the plastic holding the washer together, which made the plastic unable to hold the washer, and also made it impossible to remove the screw and washer. I managed to remove the screw by breaking it in half (luckily it looks like there are some spares), but now I can't tighten that side. Is this going to be an issue? It seems like the motor is in position, but I don't know how well it will stick with just one side tightened. I also don't know if I can remove the other screw without breaking it now, considering the previous example. Any recommendations on what should be done? Should I pause assembly and try to obtain a new piece for this?
Thank you!
Re: Y motor holder damaged during assembly
Depending on which screw it was, I think you can temporarily secure the piece by passing a bolt (with a washer) from the INSIDE of the printer and out the rear bracket. Secure the bolt on the outside with a nut. You'll need to verify that the bolt head clears the motor pulley. One of the screws has less clearance between it and the pulley. So, definitely check the clearance.

Good point! I tried flipping the bolt for now. I didn't add a washer to that side for now though, and that gave it enough clearance. It's the one right next to the motor, so I don't think I can use a washer...

As long as the fix holds enough to print a replacement motor holder in PETG you should be fine. The STL files are available at

Once you have a replacement and a spare printed swap out the damaged part.
It is advisable once you have your printer up and running to print of a set of spare parts. In particular the extruder body and cover.

If your re-printing parts, you may want to consider printing improved parts.
This guy does some really good designs and has an improved Y axis motor holder.

Normal people believe that if it ain’t broke, don’t fix it. Engineers believe that if it ain’t broke, it doesn’t have enough features yet.
