I'm thinking about how to mount the hot end to my prusa. It is my own design, but based on seemingly the most common design of hot end out there at the moment. It has a PTFE barrier joined to a nozzle via a PEEK part. The assembly is held together by bolts running through the PEEK, and then up through the x-carriage and then the extruder mounting holes (see attached render) I am slightly worried that this arrangement will snap my X-carriage (ABS, a Nophead print), as it will have the extrusion force coupled directly to it. I was wondering anyone has tried this arrangement before, and how well it worked? Has anyone ever snapped a carriage, and how much force did it take? https://reprap.org/forum/read.php?151,98314,98314#msg-98314 Wed, 10 Jun 2026 17:39:04 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?151,98314,98393#msg-98393 https://reprap.org/forum/read.php?151,98314,98393#msg-98393
Regardless, I still had on occasion the exact setup shown in the original image and it worked fine, albeit a little tricky to put together and take apart on a frequent basis.

Cheers,

You could add a metal plate to take the force.]]> nophead General Mendel Topics Tue, 20 Sep 2011 15:21:35 -0400 https://reprap.org/forum/read.php?151,98314,98314#msg-98314 https://reprap.org/forum/read.php?151,98314,98314#msg-98314
