This is a version of bwevans "Mosaic Feet & Spool Holder", adapted to use M8 threaded rods and 608ZZ ball bearings.
The attached stl and scad files feature a slightly taller foot with a 8mm hole instead of 6mm.
Here is a short time lapse video of the spool holder in action: youtu.be/UQoSdxPS8tI
Things you will need to complete the build:
- 4x 608 ZZ ball bearing
- 20x M8 washer
- 16x M8 nut
- 2x 180mm M8 threaded rod
- 2x 140mm M8 threaded rod
- 4x printed mosaic_feet.stl
I ordered the ball bearings from ebay and got the M8 nuts, washers and a 1 meter long threaded rod from a local hardware store.
Choose a length for the threaded rods to match your spool sizes.
I cut mine to 180mm long and 140mm wide.
Assemble two sides using the top holes in the feet. The order for a side part is: nut, washer, foot, washer, nut, [space], nut, washer, foot, washer, nut.
Then connect the two sides with a threaded rod thru the bottom holes. The order of parts are: nut, washer, foot, washer, ball bearing, washer, nut, [space], nut, washer, ball bearing, washer, foot, washer, nut. Adjustable size filament spool holder
