Hot end Bowden tube cutting.

I’ve just fitted my spare bit of tubing to the hotend as the original has shrunk a little causing jams. All good but obviously that bit is going to need replacing quite often. Ordering direct from Prusa to the UK is expensive and due to Brexit can be a right pain. So I have ordered some tubing from E3D. Cutting to length is not a problem, but the drawings show it chamfered at each end. What is the best way to do that, I’d do people actually bother?

This should also help: How to trim PTFE tube - Original Prusa printers | Prusa Knowledge Base (prusa3d.com)

And this is the same Jig provided by @stinkypete on Printables: PTFE Tube Chamfer and Cut Jig

And the chamfer is important especially where the PTFE tube meets the heatblock.

Many thanks for that. I guessed it was important given the tiny bit of shrinkage on the original part made such a difference.
