Lid for Mazzer coffee grinder doser

The Mazzer Luigi coffee grinders are great machines, and total overkill for use at home. They last forever. Unfortunately, the lid for the doser on my model was made of some thick but very frangible plastic. I dropped it on the floor once and shattered it. I assume replacement parts are available for this, but they're probably expensive. If I still had a wood lathe, I could have easily made a replacement that way. But a while after this happened, I did get a 3D printer, and made this part. 

The Arabic script on the top says “bunn," which means coffee (beans).

You should enable supports for the overhanging edge.
