A cylindrical container for various small parts in various sizes. Diameter (D) and height (H) are inside dimensions; the D26 H56 for example can store 25 2€ coins. Scale up/down moderately to suit your needs, height (z) can be scaled independently of x/y.

The lid can be used the other way around, there's a slit for using a coin or similar to turn it.

I recommend using different layer heights for body and lid for smoother operation (like 0.20mm and 0.17mm).
