Summary

This uses the superb CrushGrind 25 ceramic grinder mechansm.

Okay it looks more like a thermos with a handle than a klien bottle. Not to mention it is two color. I thought I had enough filament for both parts. I didn't. (obviously)
It is mainly provided here as an example to demonstrate that thing #3090525 works.

Should anyone want to print one of these:
Print the top without supports. The bottom need support only for the rim that the mechanism seats against. Print it with support touching build plate and 45 degrees.

To assemble, carefully align the parts and press into place. The tolerances are intentionally tight to prevent any slipping so you might have to adjust for your printer.
Use good judgement on which filament you use. It should be food-safe.

The design is available on Onshape https://cad.onshape.com/documents/4487c204ce73b189b984f887/w/13b5355c94616d2c05a6f16d/e/5f65ae8d6b5f238627822e62

BTW: For best results, of course, you need a 4D printer.
