Bambu Lab X1C P1P Foldable offset back spool mount

This is a simple remix of Ebolo's Foldable Side spool mount for X1C and P1P. My printer shelf has more room at the back then side of printer, so this one is a back mount that offsets the spool holder near machine center, so I can remove spool from the spool mount without hitting the shelf column. I have also added a few holes to the offset mount that holds the alien wrench and nozzle needle. Very situational, but if you have a shelf like mine it might be useful for you. ----- 2023-08-11 ----- I have added a V2, which secures the mount to the top center screw at the back of the machine. The main reason for this redesign is: the old mount is showing some small deformation - the arm is longer, and the PLA I use is not strong enough to hold full spool without deform. It likely is not a major issue, as I can see it won't deform further, but the top mount method should eliminate the worry that spool might fall out mid print. The back of my machine is getting a bit busy now. PTFE Wye, split coupler.. etc. I need more room in the original corner where the spool holder was mounted with V1. ----- 2023-08-28 ----- Added a compact roller, remixed from suit's compact filament roller. I made some modification as while suit's model uses 8x22x7 bearing (608), I only have 5x16x5 bearing (625). So this roller is even smaller than suit's roller, and it can be added directly onto my v2 design and still folds up. I think I finally is happy with the back filament mount design now..
