4mm Tube Cutter PTFE

I found cutting ptfe with a sharp knife is simple but if its not 90 degree filament catches in a push fitting.

This block always cuts perfectly using a 0.7mm blade (box knife)

The block can also be used to hold tubing while drilling. I added slots at other angles 30, 45, 60

The block is of such a size so that it can be held safely
