PTFE ruler cutter

This is made to keep PTFE tube firmly along a ruler, and cut it at a precise (long) length.
Just print it twice and use one at 0mm, the other at the required size.

Add supports for bed only.

I made it to easily cut a highly curved PTFE tube, at 360mm, for MMU2S, and other required sizes.

2 ruler sizes : 25.6mm and 28.5mm. Ask if you need another size !
