first version. still needs a little aerodynamic trickery, to drop coins more reliably, and more filters. parametrization would be nice, obviously. designed for 38mm, you could scale the whole model for other diameters but if you go to small the 2€ won't fit anymore, I guess
the flask has a M36x4 thread, if you wanna design your own reservoir. yes … the one I printed is very small lol
The author marked this model as their own original creation.
