Coffee Knockbox

An espresso knockbox that really works for me. The upward pricks pierce into the dried 'cake' of coffee grounds that can be quite stubborn to remove when properly dried.
I separated two files because I placed them separately into Cura Ultimaker as to give different print settings to each section. They overlap in the disk that makes the base, so that the columns support the impact all the way to the bottom with higher infill and wall thickness. I went by this link to guide me through achieving this on Cura https://3dprinting.stackexchange.com/questions/6522/different-infill-in-the-same-part/6523

The base(cup) I printed with:
- 20% triangle infill, but 10 might be fine,
- 1.2mm wall thickness,
- 0.12 resolution,
- and 0.84mm top/bottom;
- fan speed at 20%;
- 105% material flow
- no support or raft.


For the columns I changed:
- 2mm wall/top/bottom thickness
- 80% infill
