35mm PTFE Cutter

This is an original design of a 35mm PTFE tube cutter for my Monoprice Maker Select V2. It cuts 4mm PTFE (teflon) into perfect 35mm segments at a perpendicular angle. Do not upscale or downscale as there should be enough tolerance for any printer and should be just a little snug (hole is 4.5mm). Cut using a razor blade or X-Acto blade. Use a rod/stick/allen key to push the newly cut piece out from the smaller left side hole.

Added version with much tighter 0.4mm gap for thin razor blades
