If you want to just clear the little bit of retained grounds or chaff in your Zerno Z1, this bellows can help you out.
This 3D printed Zerno Z1 Bellows is a flexible piece that fits in between your Zerno Z1 stock hopper and stock lid and transforms it into a blower. If you don't have the lid, then I've got that covered as well.

Well made, works really well! The Z1 should come with bellows from factory. The grinder has a lot of static and can have retention as result. This completely fixes the issue.

I purchased the Z1 because I wanted one good grinder and this thing has delivered. It is a beautifully crafted machine and runs impeccably!
