These files are the Fusion 360 source files of this project.

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.

Thank you to Banggood for providing me with the Ender-3 V2 3D-printer.You can buy one here:https://www.banggood.com/custlink/3v3hCfiZyI
