If you want to go this route, prepare angle grinder :)
So far there are 2 main components:
- Funnel which I use with printed TPU bellows. This is press fit and should be fine for the angle of legs
- Legs and spacer to support the grinder in an angled orientation. Legs should be printed twice and they fit to the bottom legs holes (no legs needed just some washer and screws). The spacer is there to make the whole assembly more stiff. It is not necessary but highly recommended - use some connection material as well.
- Coffee exit: print with 0,2mm first layer followed by 0,1mm rest (for smoother surface so the coffee does not stuck too much inside. It is important to cut the grinder original part with angle grinder and file it (for smooth edges). There is a photo in the library how it should look. The coffee exit should be able to be pushed 16mm deep which should be right to the end.
I will add the files as Im making some progress - next step is to do something with the coffee still being stuck in the shute even with angled.
