Is It Really Indestructible? SHREDII 4.0 vs Nokia 3310

Mini DIY shredders are now a reality with our latest SHREDII 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, our DIY injection molding machine, to create new plastic injected parts. 

This SHREDII is designed for use with Nema 34 motors, and in this video we also tested it with more powerful servo motors that we had left over from our DIY CNC and DIY wire EDM machine videos. 

We hope this DIY shredder will enable those with minor shredding requirements to continue moving forward with their recycling projects.

Shredii

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!

SHREDII 6.0 Review

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.

Custom safety cover

I purchased the SherdII and down loaded the round safely cover. But I needed a taller cover. I contacted customer service and a very nice gentleman responded. I explained what I was looking for. He had design create a file for me to download. I printed it and it works great. It was just what I needed. Their customer service is amazing. I highly recommend them.

Thank you for the 5-star review Alicia! We love your setup and we're glad you're getting great use from your SHREDII!

SHREDII Review

I just finished the assembly and delivered the finished shredder to my former employer. The assembly was easy however the two holes to secure the gear cover were not tapped. The shredder will be used to breakdown plastic parts that have failed production so that Melt Flow Analysis can be performed on the plastic. In order to perform Melt Flow Index testing, you need to have the plastic ground up into manageable chunks. The plan is to use SHREDII to grind up the questionable plastic when we have to analyze a future production problem.

Thank you for your kind review, Ross!

Great little shredder for my shop

This shredder works great, especially with plastics. The hand crank is a nice to have, but I think I'll stick to using motor.
