Click&Fix Filament Spool Bearing Railway - Flexible positioning, for any common spools, works for any length

Update April 1st, 2019:
These parts are working perfectly for me since more than 3 years, but some of stl files are not compatible with all slicers. I designed all parts new, more clean and easier to print. Additionally I designed the Spool Guide additionally as two parts positioned flat on printers surface and mounted together with the bearings and screws! Try 'Spool_Guide_Flat2Piece' if you encounter problems with overhangs in the thread. Mounting and Support part are new as well. Alle new pa
