Summary

I sometimes switch between grinds depending whether I'm making espresso, or a pour-over. Occasionally I forget to change the grind and waste beans. This replacement for the bellows cap reminds me every time. One side indicates the grinder is setup for whatever espresso beans I have at the time, the other shouts “Filter” to let me know it’s set up for my pour-over.
Just replace the standard cap with this. It works great!
I used PLA on my Bambu P1S. Colour was by layer, getting aboiout .6mm colour thickness top and bottom.
