Coffee grinds bin

thingiverse

Tamp box or knock box to hold coffee grind waste before adding it to your garden. Best print the body in PETG to absorb impacts. Print the foot in TPU so the unit won't mark your benchtop. This bin is designed to hold a 20mm PVC conduit, also a 3/4 inch may work, however I haven't tested this. The conduit serves as the knock bar, resisting heavy-duty whacks from the metal tamp and easy to clean. v2 is a slight variation with an angled front, the tamp bar shifted slightly, and a rounded base for easier cleaning.
