Sugar or Salt Dispenser

thingiverse

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 (corrosion does happen, but is not a health risk). But that's the downside: You need 4 steel washers (inner diameter: 15 mm, outer diameter: 44 mm, height: 3 mm) and drill some holes (see below) - which I couldn't do without a drill press). I included a plastic version of the washers as a modell and as a test for the hole design. So you can deside after printing whether to take the effort to find an open workshop (www.hobbyhimmel.de) and drill these holes. When using it turn the two parts clock wise, so they rather close over time. I added the autodesk-fusion file (even though it's a mess) in case someone wants to adapt the dose.
