I ordered a 1000+ assortment of screws, and they were all mixed up. So i built a set of sieves. This design works with M5, M4, M3 and M2 mechanical screws (cylindrical head with hexagonal inset).

For the next iteration, I'll design more sieves sozes and add an interlocking mechanism to stack them firmly.
