Flat Pack Grinder

Hello all

I'm here to present a small school project. I had to develop a sort of grinder for vegetables only using 2D parts. Which makes it a flat pack product. My goal was to exclude bindingmaterials like glue out of hygienic reasons. Due to a short amount of time I wasn't able to work this thing out to it's full potential, so don't be made if doesn't work properly. On the other hand, suggestions are always welcome.

These are the materials and tools that I used. You don't necessarily need a lasercutter, but if possible, it makes some things a lot easier.

The materials include balsawood, a thin sheet of milky transparant PP (1 mm), a thick plate of milky white PP (5 mm), some stretchers (I still need to work on that, it snaps a lot), small rings with a screw-end (D: 2 mm & L: 8 mm) and some small sheets of metal (thickness: 1 mm, L: min. 20 mm & H: 60 mm).

I think I don't need to explain which tools I used. They're basic enough. Bores to use: 1 mm, 1.5 mm, 2 mm
