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.
The fusion 360 source file option includes these formats:

The STL-files option includes these formats:

*Note: Only the individual 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
*Note: The Fusion 360 source files option is an archive of the entire project so this includes the shredder and the gearbox, no need to purchase the Fusion 360 source files of the gearbox seperately.
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.
