Homemade Shredder Recycles Circuit Boards | SHREDII 5
After many iterations, we have finally made mini DIY shredders a reality with our latest SHREDII 5 design. This homemade shredder was tested against wood, plastic, aluminum, steel, and even the indestructible Nokia 3310. This shredder is a great addition to our DIY machine shop, and we use it primarily for recycling 3D prints by taking the granules that come out of the DIY shredder and using them with INJEKTO 2.0, our DIY injection molding machine, to create new plastic injected parts.
This SHREDII is designed for use with two horsepower AC motors and two high torque gearboxes, and in this video we also tested its strength by shredding pure copper rings that we have leftover from a DIY vacuum furnace that we are building. We will be releasing that video along with a new DIY CNC, DIY Lathe, DIY Metal 3D printer and DIY EDM V2 videos in the near future.
We hope this DIY shredder will enable those with minor shredding requirements to continue moving forward with their recycling projects.

Customer Reviews
Recently we purchased your key chopper, and we must say it's an impressive tool for destroying keys. We used to cut them up with linemen's plyers by hand, so as you can imagine your tool not only saves time but also prevents a possible hand injury so it's also ergonomically friendly. Time will tell on longevity on the blades however its well-constructed, however adding a catch basin to the bottom would be an added plus also a cover for the funnel feed with a slot would also prevent pieces from popping up in the work area. Just some feedback. Thanks much, Mike Wooley
Shredii 8 is a really impressive machine. it can chew through pretty much anything you can do with a 3d printer.
its great for chewing up big filament into small scraps for recycling. The crushing does generate a bit of heat which you need to keep an eye on if you are using low temp materials like PLA. But that is to be expected with machinery. Use in moderation.
The safety switch is a good move too. I was annoyed at first that you have to hold down the on switch, but in retrospect, its a very smart move. It greatly prevents accidents. if you feel you are in danger, let go of the switch and the machine will stop IMMEDIATELY.
Its a well rounded desktop shredder. If you have a lot of waste and want to turn it into something useful again, Shredii 8 will do the job!
The SHREDII 8 hits the perfect balance for users needing a small-footprint shredding solution with industrial-level performance. Its modular kit nature, high-grade steel components, and stellar support make it both a practical tool and a fun project for anyone serious about responsible disposal and material recycling.
Love your setup, and glad SHREDII 8 has met your needs! Thank you for the kind review.
The motor really changed the game with Shredii. It was a bit of a challenge to attach the motor since both the motor and Shredii are quite heavy, but once together it was definitely worth it!
Finally got my Shredii 6! It feels like a beast. Also got the tall safety funnel to throw more stuff in at a time. I'm happy with my purchase.
