This is a simple PTFE tube cutting guide to help get a straight line when cutting a PTFE tube.

The model requires no supports and can be printed laying flat with no issues.
I used PLA and it worked well.

It is built to be used with an exacto to cut PTFE tubes.
The recessed part is to help hold the ptfe tube while cutting. I built this model after getting frustrated how my cuts were not at 90 deg before I began to use this guide. Now it is how I wanted it to be.

A ruler is printed on the side (dimensions are in mm) to get an approximation of the lenght that is in the guide.

Le longer part is to ensure that the ptfe tube is well aligned when cutting it on the other end, because most often PTFE tubes are curved when we receive them.

Enjoy! And don't hesitate to notify me if you think I shoud add or modify something.
