PTFE Chamfer Tool

This is a tool I designed to chamfer the ends of PTFE tubing. I was having issues with some PTFE connectors where the filament would catch on the edge of the tube and cause overload errors. The chamfer angle is approximately 70 degrees from horizontal. There are two holes for the tube: the hole near the tip of the blade is for chamfering the inside, and the other hole is for chamfering the outside of the tube. The outside chamfer is useful for sliding the tube into custom connectors that are a tight fit. I have tested it with both the Capricorn tube and Bambu tube. For assembly, you will need: 2x - 3x M2 screws 8-10mm in length. 1x #11 exacto knife blade, https://www.amazon.com/Profession-Modeling-Scrapbooking-Stencil In the model pictures I only used 2 M2 screws, the one at the top goes through the hole in the blade, and the one in the middle is to lock the blade in place. There is an optional third screw hole that pushes against the back of the blade if you have issues with the blade
