PTFE tube beveler/cutter thing

thingiverse

So after trying out several existing PTFE beveling and cutting jigs that mostly got the job done, I came up with a few ideas for improvement and decided to implement them right away. Here's my take on cutting and beveling PTFE tubes. The jig consists of two main parts: the body and two screws that clamp the parts together securely. The body part has slots cut into it specifically for the cutting blade, allowing for precise control during the cutting process. To assemble the jig, simply insert the PTFE tube into the tube holder, which is then sandwiched between the two body parts. The PTFE tube is locked firmly in place with a nut that features a tapering thread. When tightened, this nut clamps the PTFE tube securely. It's worth noting that PETG can become quite sticky to turn, so applying a bit of lubricant to the nut thread may be helpful. Alternatively, you could print the nut using PLA or ABS. Once the jig is assembled and ready for use, cut the straight end of the PTFE tube first, followed by beveling the end if needed. To do this, simply insert the blade and turn the tube holder to achieve the desired angle.
