Stackable Nut And Washer Sieve Tray
A 110 x 110 x 30 mm sieve tray for sorting a can of mixed nuts, washers and small screws. It has a 2.4 mm floor with a hex grid of 6.5 mm holes, so anything with a smallest cross-section under 6.5 mm drops through when you shake it. Each tray has a chamfered 104.4 mm spigot on the bottom that seats 0.4 mm inside the 105.2 mm rim of the tray below. Reprint it with a different HOLE value to make a coarse-to-fine sieve stack, then tip each tier out through its finger notches.
