Plastic shredder

It's possible to shred plastic scraps with a blender, but doing that is tedious and not scalable. I hope to recreate a fine-particle shredding system that uses 3D printed components!

Created the Plastic Pot

Today, I created the starting phase of making the plastic pot. here, plastic will be inserted, grinder and then will naturally fall out through the slot. I especially designed it for 3D printing: the outer geometry is polygonal, while the inside is a smooth bowl shape.

Brainstorm + Inspiration

A fellow Youtuber was able to create a plastic shredder using an angle grinder. His project uses a lot of metal components and off-the-shelf hardware, which I believe is slightly limiting. I aim to incorporate 3D printing to create a design that is both efficient and cost-effective.
