3D-printed shredder

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 just 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:    • 3D printed high torque servo/gearbox ...  
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.
