3D Printer Part Recycling Grinder

I was getting tired of cutting up failed parts and my research materials by hand. So I decided I wanted a part grinder to compliment my Filastruder. There are a few options for grinding up failed printed parts for turning them back into filament. I didn’t want to spend $500+ dollars and also wanted something that was more effective than the other low cost DIY solutions I’ve seen. I don’t have access to a machine shop anymore so I had to make something in my garage with somewhat basic hand tools. The design is based around this tooling restriction. It is smaller than I would have liked and took about 40hours to build.”
