This is a flange that attaches to the Shredder Mini that Sustainable Design Studio makes. The flange gives the shredder a lip that makes is easier to attach a tunnel to that you can feed items down to the shredder. I use the shredder for shredding Bambu poops, print mistakes, etc. The tunnel keeps all of the tiny bits contained and gives the shredder a hopper so I can shred continuously without having to stop as much. I also created a lid for the flange for safety and to keep the shredder clean of foreign objects.

The flange attaches to the shredder with six M3 screws and six M3 nuts. The tunnel and lid rests on the lips on the flange when in use.
