Dry Box Spool Rollers
thingiverse
Uses M3 hardware. Recommend M3x6 / M3x8 bolts. - For M3x6 you may want to edit the F3d file's "Base_Height" parameter from 4mm to 3mm. All models will update accordingly. These spool rollers use the 608zz Bearings. I made these so that I can have all my spools in line with each other, using 2 8mm rods as guides. The dowel rods I bought were from Home Depot for like $2. Print all brackets except the threaded ones on their sides, so no supports are needed. The threaded ones I recommend upright for better threads. A small amount of support material will be required.
