Download Free 3D Model Prusa Multimaterial upgrade heatsink PTFE cutting jig – 41mm 3D Print Model

Summary
A very simple jig to enable precisely 41mm of 4mm OD PTFE tubing to be cut to insert into the top of the MMU heatsink. Insert tubing all the way into the hole and cut parallel and flush with the wall at the entrance point.
Please note that this is not the only step required with this tubing. It must also be reamed and chamfered (official specs here). Also note that the inside diameter of this tubing is specified as 1.85-1.9mm, which is not the same as you will find on generic PTFE tubing.

Use a small brim and print vertically. I printed this with 4 perimeters. Insert tubing all the way to the end of the jig and wse a razor or utility knife blade and cut flush with vertical surface at entry point.
