Spool Holder adjustable with bearings for Prusa i3 MK3S. The original spool holder, not the printed double holder version delivered with the original Prusa MK3S, is not ideal for smooth filament unwinding. So I designed and created my own solution. Key features include: * Adjustment for Filament spool PM and Filament spool Prusament * Easy unload/load of Filament spool * Simple mounting/demounting and positioning of bracket arms * Very easy unwinding with minimal rolling resistance * Adjustable unwinding resistance, now upgraded Printed parts are made from PETG material: * Layer height: 0.2mm * Infill: 30% Grid * Vertical shells perimeters: 3 These printed parts include: * Pos-001_Center bolt * Pos-002_Center nut Additional printed parts, also made from PETG material, are designed with the following settings: * Layer height: 0.2mm * Infill: 20% Grid * Vertical shells perimeters: 3 These additional printed parts include: * Pos-003-01_Holder arm L * Pos-003-02_Holder L * Pos-004-01_Holder arm R * Pos-004-02_Holder R Purchased materials are used for assembly: * 2x KINEX Ball bearing 606-2Z (606ZZ) * 1x Rohr 8x1 AL length=102mm * 1x DIN 976A Threaded rod M6 length=160mm * 4x DIN 985 Hexagon nut with polyamide thread lock M6 * 4x ISO 4762 Hexagon socket head cap screw M3x16 * 4x ISO 4032 Hexagon nut M3
