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 8 for 3d printers

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.

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!
