PTFE Tube Guillotine Cutter

myminifactory

Getting a perfect 90° cut on PTFE tubing is an exercise in frustration. If it's not spot-on, you're inviting leakage, which is never acceptable in any situation, particularly in a 3D printer hotend. Disassembling the heatblock to trim the tubing flush against the metal sleeve isn't exactly enjoyable, either. What you need is the PTFE Tubing Guillotine! Simply slide your tubing through the hole until it sits firmly inside the rear pocket and slice. Easy does it. You'll require a 25mm (1") long 3mm bolt, a 3mm nut, and two or more 6mm long 3mm bolts as well as a standard Stanley-type knife blade. UPDATE As requested, I have added another version of the base that features the PTFE tubing hole cut all the way through to simplify removal of the scrap piece. This is v3 of the base.
