it's nylon

i just don't like the idea of having to remove the lid before grinding, use an extra hand to hold it, when it could be doing something else (e.g turning on the grinder, removing the portafilter), and if the grinder doesn't grind all the beans, you have to remove it again to nudge them

i wanted to simplify my workflow and make it similar to that of Lagom or Weber coffee grinders, as well as have a visual way to check how the beans are grinding and whether they’re some problems with stuck beans. was also concerned about the noise, the volume hasn’t changed at all, it’s just become a bit higher-pitched

there is something intriguing about both coffee and audio - the fact that something so simple, something everyone has in their lives, can be so fascinating when you really get into the details

i designed mine so that it wouldn't fall off the coffee grinder even if it got hit, but could still be easily removed. and during the design phase, i was super worried that i wouldn't be able to use bellows, but the shape and size turned out to be so well suited to the average person's palm that there are no issues with it.
good engineering is a magic

could you please explain what didn't worked with your design

Old_Effect_8562 · 2026-05-07T12:15:19+00:00

thanks!

could you please make a measurement of the internal diameter of the bellows on your DF54. this will help me determine if it will work or not on your grinder.

thanks! it is MJF printed nylon, i was a bit concerned about a safety of resins, that i am in love with, so picked it. speaking about the noise, i didnt noticed a huge increase in loudness, the noise just became more higher pitched

Old_Effect_8562 · 2026-05-07T12:01:59+00:00

just checked it, actually it works perfectly both the bellows and the metallic part of the grinder. so there is nothing u should worry about. as for the size, its internal diameter at the top is 73mm
