PTFE cutting jig for Dragon hotend

prusaprinters

<p>I printed the fantastic Dragon hotend mount from Sebastian (https://www.prusaprinters.org/prints/63259-prusa-mini-mini-dragon-hotend-mount) for my Mini but I was having too much difficulty getting the length correct for my PTFE tube between the PC4-M8 fitting and the mount since I don't have passthrough ones as well as getting perpendicular cuts without it wandering off. Enter, this jig. It's designed with a hole big enough for a PC4-M10 fitting that reduces down to a 5 mm hole through the center of the jig. It should give you about a 15 mm section of tubing using the narrow guide slot for your blade. I tapped the threads for the fitting but you might be able to get the fitting to cut it's own with some persuasion. Any material should be suitable. More than 5% infill should give it enough strength, though you may want to go higher around 15 or more if you don't have a tap handy.&nbsp;</p><p>Note: I designed this for the blade to use the face closest to the fitting as the reference for cutting. Should you need to reduce the length, the guide slot is ~1.5 mm across and the middle post is about 4 mm wide.&nbsp;</p>
