I wanted the salt and pepper mills on my dining table to look better so I designed new housing for my existing mills. 

I noticed that I have multiple kinds of mills that look the same but don't have the same fitment. The model fits the mill that has transparent plastic on top, see the photos. it will not fit the one that's all black.

The ones I have printed uses "Copymaster3D dark blue" and "CCTREE polychrome marble" I've made filament changes at 0.6mm on the top model and 80mm on the bottom model.
