Coffee Knock Box with Integrated Desiccant Compartment

This knock box makes cleaning up after espresso prep quick and mess-free — just knock out the spent puck against the internal bar and empty it out when full. What sets this design apart is the base: instead of a simple cap, it's a dedicated compartment that can be filled with silica gel or another desiccant. This keeps residual coffee grounds dry between uses and helps prevent mold and odor buildup, especially useful if the box isn't emptied every day.

The base attaches with a quick-release bayonet twist-lock — just push and turn a quarter-turn to open or close, no threading required. Printed in PETG for durability and easy cleaning.

Parts included: body, lid, knock bar, and desiccant-compartment base.
