Coffee grinds bin

thingiverse

Tamp bin or knock box to hold your coffee grind waste before you put it into the garden. The body is best printed in PETG to absorb the impacts. The foot can be printed in TPU so the unit will not mark your benchtop. This bin is designed to hold a 20mm PVC conduit or a 3/4 inch may also work, however I haven't tested this. The conduit is used as the knock bar as it better resists the heavy-duty whacks from the metal tamp and can be cleaned really easily. v2 is a slight variation on the bin, with an angled front, the tamp bar shifted slightly and a rounded base on the inside for easier cleaning.
