Hopper for paper/CD shredder

This is a hopper to fit into the opening of a heavy duty home office paper shredder, which is also capable of shredding CD/DVDs. I'm using it for reclaiming/shredding printing waste and other plastic products that can be re-extruded into filament. This is the largest hopper I could make on my Prusa i3 MK3 printer in one piece and is designed to rest firmly on top of the actual shredding unit. A large opening must be made in the top panel of the shredder. I used hot glue to secure the hopper to the top panel.

The opening of the shredder is 20x230mm, but I made the opening from the hopper slightly smaller to keep scrap from going to the edges of the shredder.

I hope you find this useful. I added Fusion 360 and STEP files so you can more easily make adjustments to fit your shredder and/or printer.
