Spaghetti too long? No problem.

This Shredder breaks your Spaghetti into smaller pieces.
Sounds stupid? Well...

Every part can be printed without support, but they must be rotated correctly.

The shafts are press fitted into the wheels. The tolerances are quite tight, meaning they might be too tight or too loose. In that case shaft1 can just be removed as it is not really necessary.

I used these 3-12V motors (same model available from different sellers): https://www.amazon.com/dp/B08CMPBXNL/

You will need the following screws (and nuts). You can also use longer screws for all, they will just stick out more.
2x M3x30
6x M4x18
3x M4x20
6x M4x30

You will need to cut some plastic for the covers. One piece that goes on the wheel and one that goes on the shoot. I just used the plastic case that came with the motors, but you can use any light plastic.

Enjoy!
