Kingrinder P-Series Screw Cap for Grounds Storage (Travel Lid)

This is a custom screw-on cap designed for the Kingrinder P-Series manual coffee grinder. It threads directly onto the grinder’s grounds storage area, allowing you to securely seal and transport freshly ground coffee.

I created this because I wanted a simple way to grind coffee at home and bring it with me to work without needing an extra container. With this cap installed, the grinder becomes its own portable grounds jar — compact, clean, and convenient.

The cap is easy to print and does not require any supports. It uses the existing grinder threads and fits snugly for reliable transport.
