Solar Ball Mill

thingiverse

I lost my job due to the pandemic known as COVID-19, but it gave me a chance to study extramural 3D design using the free time I had. This is my first project, so I'm asking for understanding from people who are familiar with this topic. To get straight to the point, I've created a small ball mill that's adapted to fit inside a jar with a diameter of 6cm - it can grind about 200g of coffee from Tchibo. The power comes from two 110x60 6V solar panels connected to the TP4056 system and 16340 batteries. A 6V motor drives the jar, which is also fitted with glass balls for grinding. To assemble this project, you'll need six M3x10mm screws, two M6x30mm screws, and ten pieces of M3 nuts. If you find this useful, please let me know what you think it's worth in exchange for my payment - I'm open to suggestions.
