For my filament box I wanted to have a spool roller with following features:
- Shall save space in the filament box.
- Enable easy replacement of filament spool.
- Shall work for 1kg spools with ⌀200mm.
- Shall be robust and avoid jumping out of the spool.
- Shall be adjustable in a wide range to fit for spools of different vendors.
- Material usage shall be less.
I didnt find any spool roller which fits to my needs. So I have designed my own one. Goal of the design was to print much parts as possible and print should be without supports. Nuts which fix the ball bearings are self-locking due to friction between spool and washer.
Part List:
- Printed parts are made of PETG | quantity: 1 (see STL)
- Ball bearings 6282RS (d8xD24x8) | quantity: 4
- Cylinder screws M3x10 | quantity: 4
- Washer M3 (ISO7093) | quantity: 4
- Hexagon nuts M3 | quantity: 4
Assembly Instruction:
- Mount ball bearings to side plates.
- Add washers with side of the shoulder to bearings.
- Assemble nuts (2 left-hand thread and 2 right-hand thread).
- Insert nuts to screw plates.
- Join side plates together.
- Assemble screw plates and fix parts using cylinder screws and washer.
- Adjust filament roller to the size of your spool.
Enjoy printing with your new filament roller.
