Fellow Opus bellows lid

This lid is a replacement to the stock lid on the Fellow Opus coffee grinder. It incorporates a silicone bellows that can be tapped to push retained coffee grounds into the grinder's catch cup.

The bellows are not part of the printable files and should be purchased separately. The base of the bellows should be about 64mm and the height is 38mm. A shop on Etsy sells one that is compatible. 

No gluing needed, the inner part screws into the main lid and the bottom of the bellows sit inside the inner cylinder. The entire lid fits inside the hopper of the grinder.

No supports needed. Print the larger, outer disk top down and the inner cylinder threads up.

Printed using PLA or PETG.
