These designs were an absolute lifesaver. I was able to replace the PTFE tube in my Prusa mini hotend by cutting with these guides, now he's back up and printing away! Thank you for this model. I loved being able to fix my printer myself, with the help of the community of course.

Could you do one for the mmu3 please ? It has a 45 degrees and 19mm in length

@Area51

@manofthesky You can use the model "ptfe-tube-length-cut-jig-19mm.stl" to cut 19mm length and the "ptfe-tube-external-chamfer-90-v3.stl" to make the 45 defree chanfer.

Every Prusa Mini owner should print a set of these. It makes it so easy to cut and chamfer the PTFE tube exactly as needed. I did need to use a 5/32" drill bit to clean out the hole of the chamfer jig, and it's a perfect fit!

Rotating the PTFE tube inside the chamfer jig can be a little tough since the PTFE is so slippery. I found @LoboCNC’s Collet Chuck and Collet Assortment ( https://www.printables.com/model/314149-collet-chuck-and-collet-assortment) very useful for that. I used the Collet176 and it grabs the PTFE tube very nicely. (edited)

I had to scale the model up for the ptfe tube to fit.

@piegolf Thank you for sharing your experience with the model. To ensure the chamfer tool functions as designed, it requires a snug fit with the PTFE tube. Clearing any printing debris with a 4 mm drill usually allows for the proper fit without the need for resizing the model before printing. I appreciate your feedback and hope this information helps in achieving better results. If you have any further questions or concerns, please feel free to reach out. Thank you!
