Hopper for paper/CD shredder

thingiverse

This is a custom hopper designed specifically for the opening of a heavy-duty home office paper shredder, which also effectively shreds CD/DVDs. It's being utilized for reclaiming/shredding printing waste and other plastic products that can be re-extruded into filament. The largest hopper I could create on my Prusa i3 MK3 printer in one piece is designed to rest firmly on top of the actual shredding unit. A significant opening must be made in the top panel of the shredder. I utilized hot glue to secure the hopper to the top panel. The opening of the shredder measures 20x230mm, but I made the opening from the hopper slightly smaller to prevent scrap from going to the edges of the shredder. I hope this is helpful. I have included Fusion 360 and STEP files so you can easily make adjustments to fit your shredder and/or printer.
