PTFE Tubing Cutter

thingiverse

Hello everyone! I couldn't find a decent PTFE tubing cutter that used standard utility knife blades, so I decided to spend too many hours over-engineering one. Used for getting a perfectly square cut on 4mmOD PTFE tubing. Demonstration of cutter in action: https://youtu.be/gvNfBubcs98 Release the preload on the spring when you aren't using it, not sure if it will lose it's springiness if you leave it like that for months, but it probably will.
