Sugar or Salt Dispenser

I had built a sugar dispenser quite similar to the existing ones (for example https://www.thingiverse.com/thing:724273 and https://www.thingiverse.com/thing:707060) only to find out after a while that my brown sugar slowly grinded the petg so I had barely visible parts of plastic in my coffee. Same thing with my nasal douche/salt dispenser.

So I created a new version. Elegant design, precisely 2.1 g of salt, see video) and the moving parts are steel washers - so no more plastic in your coffee
