Bambu Lab P1P Side Spool Holder - Filler Adaptor

I really liked the side spool holder for the P1P remixed by Sonnyc as my P1Ps are on some rack shelving and there's no space at the rear for the standard spool location. 
However, using the stock pressed metal spool holder on the side was creating a lot of issues with my 3DQF cardboard rolls (drag and jamming). I had a bunch of Filler Roller Spool holders by HugoG pre-printed so I designed a simple adaptor to use the existing mouting screw holes.

2 versions - one is just the adaptor, the other has an arm with a threaded insert to accept a PC4-M10 coupling to act as a guide and attach a length of PTFE tubing to the rear coupler.

STLs are in the required orientation. Just use paint on supports for the tops of the curved bits.
