Smooth A1/A1 Mini spool holder

When using the external spool holder on my A1, I had two spools fall off during the printer calibration and bed leveling process, when the head would move very quickly it would yank it of the holder, Also amount of friction and squeaking I was hearing when using the external spool holder was quite annoying so I designed this holder to fit in the existing mount with a larger flange on the end of it and 22 mm bearings for smooth operation. I printed this out of PETG but PLA or ABS would work fine as well, there is only a small support in the middle of the threeaded end that will need to be removed Parts needed:3x printer parts (threaded end, spacer, flange end)Factory A1 external mount1x M4x20mm screw2x 22mmx7mm bearings (standard skateboard size bearings)Printing:4 perimeters/walls25% infill0.2 layers were usedPETG, PLA, ABSAssembly:Step 1: Remove small support material from threaded endStep 2: Screw m4x20 screw through the threaded end till snug Step 3: Place first bearing onto the sha
