PTFE Tubing Cutter

thingiverse

Hello everyone! I spent countless hours designing a custom PTFE tubing cutter because decent ones are nowhere to be found using standard utility knife blades. It's perfect for making a perfectly square cut on 4mmOD PTFE tubing. Check out the cutter in action: https://youtu.be/gvNfBubcs98 When you're not using it, always release the preload on the spring. Leaving it preloaded could cause the spring to lose its tension if stored for an extended period of time.
