A sieve that I designed to fit into a 10 l bucket that I bought. I included the model for the bucket, but it's easier to get one from the store.
It has a coarse sieve that stacks on top on the fine sieve, but each one can be used separately as well.
The coarse sieve has holes of 12.5 mm by 30 mm. The fine sieve has holes of 5 mm by 5 mm.
Supports are required when printing.
