Bambu Lab P1P ptfe tube bracket -remix

Increased PTFE tube holes by 0.1mm based upon feedback.

I changed the mount points on the inner plate to use M3 threaded inserts.

I slightly increased the M3 holes on the outer plate so the screws can pass freely.

Finally, I increased the diameter of the tube hole by 0.1mm (it was too tight for the PTFE tubes on my printers).

Hardware: Four M3 inserts with 4.6mm outer diameter and 4mm length.
