Foldable filament spool holder

thingiverse

This is my attempt to create a foldable filament spool holder with bearings for the spool. When there's a need to move the printer or free up some space on the table, simply fold this holder upwards and you're done. In its folded state, it takes only 43mm of space around the printer. Many variants are included; just select and print what variant suits your needs. Printed parts: 1x main holder 1x drum of your choice - this drum should be longer than filament spool width 1x mount of your choice - depending on your printer frame and mounting position Needed hardware: 2x 608ZZ bearing 1x M8x60 screw (DIN 933, head for 13mm spanner) 1x M8 washer 3x M8 nut 1x M3x35 screw 1x M3 nyloc nut Assembly instructions: 1. Put the M8 screw through the main holder. 2. Add the M8 Washer, 608ZZ bearing and M8 nut (in this order) and tighten them. 3. Add another M8 nut and screw it in about 35mm from the main base. 4. Insert the second 608ZZ bearing into the drum from the side with the flange. 5. Put the drum assembly onto the M8 screw; start with the side without the flange. 6. Insert the M8 nut and tighten it now, ensuring that the drum rotates freely but is secured from moving around on the bearings. If there's a problem, adjust the M8 nut from step 3 and repeat the assembly. 7. Slide the holder assembly into the mount of your choice and secure it with an M3 screw and nyloc nut. 8. Mount the complete holder on the printer frame; there must be a solid surface under the main holder in working position for it to work properly.
