Cereal Box Filament Spool Holder (608 Bearings)

thingiverse

Wanted to make a simple spool holder for a cereal box I had using 608 bearings (optional) and a small amount of filament. The cereal box I have is: https://www.amazon.com/gp/product/B07J16H8Q7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 PRINT LIST: (x1) Rod or Smaller Rod (x2) Mount (x1) Shell (x2) Cap Other: (x4) 6mm M3 screws INSTRUCTIONS 1. Put 608 bearings on the ends of each rod. If you don't have bearings, skip this step 2. Put the Caps on the ends of the rods (even without bearings). They should be very tight to prevent the bearings from sliding out. I used a light tap with my hammer to get them in. Make sure the caps are flush with the outer ends of the rod. 3. Pull the Cover over the rod + caps 4. Drill holes in your cereal box where the mounts should go 5. Screw the mounts onto the insides of the cereal box 6. Slide filament spool into the cereal box with the Rod 7. Make hole for Filament / PTFE tubing NOTES: I used a 0.4 mm nozzle at 0.28 mm layer height with 4 walls on all pieces with 20% infill. The regular rod has an 8mm cylinder, which should fit inside 608 bearings. The Smaller Rod is if your printer is not tuned exactly, it has a cylinder of 7.5mm. Both rods are 88mm long, which is the width of my cereal box. Feel free to stretch along the z axis (in Cura) to fit your cereal box.
