2020 Spool Holder

thingiverse

This is a remix of the Spool Holder to allow filament to be mounted on top of the M3D Quad Crane. I had some issues with the original so I made these. Changes to the design include: 1. Shorter height of spool arm 2. Shorter width of 2020 arm base from 30 mm to 20 mm 3. Removal of inside bearing guide 4. Added clearance for 2020 Socket head bolts 5. Bearing guide now horizontal to Z plane 6. Added Bridge plate for easy alignment between sides 7. Added T slot version so name plate does not need to be removed 8. Created tabs on spool core to snap into new flexible spool ends You will need to have 8 ball bearings - 608-ZZ Ball Bearing 8x22x7 - standard skate board type bearings - that are readily available from Amazon or Ebay for that should cost less than a dollar per bearing. Don't use expensive high speed bearings that spin too freely. Or take them from your kid's old skateboard. No additional hardware is needed. Spools come in all sizes, so this is made to accommodate M3D 1000 ft spools. Other spools work, but wider spools may need other remixed parts. 4 spools can fit across the 230 mm frame of the printer.
