A while back I uploaded a video of my 3D-printable gearbox and some people told me it looked like a shredder, I thought this was actually a nice idea so i build one. I mainly build this thing jut for fun and to show people what the possibilities are with 3D-printed parts because some people still think 3D-prints are not functional and you can only make vases, figures or boats with a 3D-printer. 3D-printed parts of course have their limits like you'll see in the video ;-). Almost every part in this build is 3D-printed, except for the shafts bearings, nuts and bolts etc.
To drive the shredder I used the gearbox I mentionned above. Video can be found here: https://youtu.be/d8us3OWgS1A
The gearbox was powered by a 3S 2200mah LIPO battery With the help of the Universal Motion Controller i made. It's possible to run the gearbox on a 6S LIPO but this would destroy the gears almost immediately in this application.

*Note: Only the STL-files for the shredder part are included in the download, STL-files for the gearbox can be found here: https://bbprojects.technology/stl-fusion-360-source-files/3d-printable-high-torque-servo-gearbox-version-2-files
Updated STL-Files info:
11/05/2022:
Small spacer between the bearing and shredder teeth was missing from the files. This has now been added.
Updated Fusion 360 Source files info:
04/06/2021:
An updated model of the gearbox, used to drive the shredder, has been implemented in the design.
The updated model of the gearbox contains:
- Minor improvements to the structural integrity of the gearbox case.
- A flat spot on the angled side of the case so washers and spacers can be mounted straight instead of on an edge.
- Minor improvement in gear tolerances.
