Spool Hanger/ Holder with bearings.

prusaprinters

My work bench is small and I wanted to save space by hanging the filament spool off to the side of my table. This is a spool holder with ball bearings to ensure smooth action. I use it for my Prusa mini Print instructions-I recommend printing the parts separately. -I used 15% gyroid infill on all the parts except the extension. -Minimum 3 parameter on all parts. -Print the cap and the extension upright. The cap on the flat side, and the extension on the filleted side.The cap and extension should be printed with an 8mm brim to ensure adhesion to the bed. -The Arm is a large piece so I used 85 speed while printing to keep the dimension within tolerance on my Prusa mini. You need: 4x 608 2RS bearings 2x M4 30mm Machine screws 1x M4 20mm Machine screw. Use the M4 30mm to attach the arm to the extension and the cap to the extension (The Screws self tap). Do this after you have slid two bearings on each side as per the picture provided Use the M4 20mm to attach the arm to the mount. The mount has 3.2mm holes for wood screws to go through. The hanger is hung under a table on the side next to the printer.
