K-cup Recycler

I made this for my Uncle. He wanted to recycle the coffee grinds for his composter and to separate the plastic and tin. I found this design but it did not use standard knives, it was loose in the slot, and the bolt and nut that I bought from my local hardware store would not fit. I provided a picture of the size of the nut and bolt needed so you know what you are looking for:) I hope this works for you and if you have any questions feel free to message me. A shorter bolt can be used than I used. This is a link to the knives that I used, https://www.homehardware.ca/en/heavy-duty-utility-replacement-blades-5-pack/p/1033004. I hope that this helps you, Happy printing:) Print Settings Printer Brand: Creality Printer: Ender-3 v2 Rafts: Doesn't Matter Supports: Yes Resolution: .16mm Infill: 18% Filament: Duramic3D PLA+ Tan Notes: It only needs support for the slot where the bolt goes. They are easy to remove. Category: Household Supplies
