So the huge important thing of the inner PEEK PTFE tube, is that the bottom side which touches the nozzle is perfectly perpendicular.
The first weeks I’ve cut dozens of small tubes which almost every time started leaking and eventually caused the filament to jam up during printing.
Until I stumbled onto some tool which is just perfect for the job. A small pipe cutter! Just cut the tube with the smallest and cheapest pipe cutter you can find.
And use a sharp blade to cut the other side to exact length. Just make sure U use the side which You’ve cut with the pipe cutter on the bottom nozzle side.

It’s not really cheap, but it’s something you can use for other things besides cutting PTFE tubing.
Ive bought mine in Belgium at a Brico store Link

Nice idea! I think I will use that for my e3D v6.

From experience of cutting 110’s of km of Ptfe tubing:

much better!

Hmmm, tbh I’ve tried to rig something together which acts as a guillotine like that. And my results where clean cut yes. But perfectly perpendicular definitely not. This might be working far better but it seems that the ptfe makes the Stanley blade cut in a curved way every single time. If that thing uses a different kind of blade it might work better than I would first think.
