PTFE tube cutting jig (45mm, 36mm, 35mm)

thingiverse

PTFE tubing cutting jig to help make accurate, repeatable and clean cuts of tubing (45mm). My use case was to use in a QIDI X-Plus (V1) normal temperature extruder. This should also work in the X-Max (V1) normal temperature extruder, and any other user that requires a 45mm piece of tubing. [edit, a 35mm and 36mm version has now also included] It took me about 5 minutes to cut 20 pieces, with zero practice. No supports are needed. I used 6 layers for the base and 4 for the wall, to help add durability for the blade running through the slot. You can use whichever you wish, and potentially modify them as needed if it wears out/cuts through with time. Measurements: Tubing diameter 4mm (hole 4.5mm). Filament 1.74mm (hole 2mm). Utility blade slot width 0.6mm. Tubing length -multiple versions: 45mm, 36mm, 35mm. If you wish to have others, the STEP file should help you adapt. To use: Slide the tubing in the full length. To help keep the tubing from collapsing as it is cut (and give a cleaner cut), slide a length of filament in from the other side to reach just past the cutting slot. Then cut with a utility knife. Usually simply pulling the filament back until it exits the tubing, then push it forward and it should eject the new tubing segment. You may choose to use the blade to push the segment back through the window, then use the filament or a piece of wire to push it the rest of the way. The slot is just wide enough for a utility blade / x-acto blade
