ptfe jig works for 4mm ptfe tube(1.75mm filament)

This is a pfte jig for cutting ptfe so they can go in the hotend flat, I've had problems with my e3d v6 bowden jamming because the pfte tube wasnt in flat and this fixed it.

works with 4mm pfte tubes which are made for 1.75mm filament.
the slit for cutting is 1mm wide.
Ignore the 2 holes for mounting, they dont work
