Reusable K-Cub Coffee Grind Collector

thingiverse

3D printed parts fit on a 2-3/4" lid diameter mason jar to collect coffe grinds from a re-usable K-cup. Fits both [single serve](https://www.keurig.ca/Accessories/My-K-Cup%C2%AE-Universal-Reusable-Coffee-Filter/p/my-k-cup-universal-filter) and Karafe sized k-cup plastic pods. I printed with 100% infill, but you probably don't have to. I also used PETG for a bit higher temperature resistance, but it'd probably work with PLA just fine. I also used a 0.8mm nozzle with 0.32mm layer height, but obviously a smaller nozzle/layer height would hide the layers better. I printed the auger upright and used supports, although there's enough of a taper on the auger that the 'support' is a thin vertical wall along the outside if you use a support angle around 55% or more. The funnel part is to direct the grinds into the jar. I printed it upside down to avoid the overhang that rests on the mouth of the mason jar.
