Inspired by some other models out there but completely redesigned/modeled from scratch. Most existing models work with the P1S mounting points so I decided to create this to place my P2S closer to the wall and save some desk space.

This design uses existing hardware to mount to the case however a longer bolt at the top is recommended since the stock one is too short to be effective. I've added the top lip to give it extra support as a result, it prints nicely but requires supports so it  can be cut if desired.

I've kept this a simple assembly using only two parts; it utilizes the stock PTFE tube holder/filament guide and the roller design is very basic, requiring no bearings. It works perfectly fine this way because the spool doesn't need a perfect, frictionless roller though if desired it could be updated to use standard bearings. As slow as the spools spin, you could even get away with no roller.

The holder is thick so it's strong but fairly lightweight; 3 walls and low 5% gyroid infill, no issues at all with 1kg spools and not a bad print time.
