Bead assortments are fun to get, but sometimes a royal pain when you need a specific size for a project and have to dig through the entire mix hunting! This is why this was one of the first things I designed when I started getting into 3d printing: A bead sifting tower.
How it works: Stack the tower with which sizes you want to sort out, largest size higher up. Snap the bottom cup onto the bottom, then pour your bead mix into the top cup. Put the lid on, and then holding the entire thing in your hand (two handed for the most balanced grip), give it a few shakes up and down and/or in a swishing motion. The beads that are the size labeled on the cup or smaller will sift through the layers until they come to rest on the layer that's too small for them to pass through, with the smallest ones gathering in the bottom cup. If some beads get stuck in a cup layer, simply invert the cup and gently poke them back out with a pencil or any other handy tool.
The sifter comes in two sizes, one with 2 inch diameter sifter cups, and one with 3 inch wide cups.
The 2 inch version comes in 3 variations, one has cups for seed bead sizes 6/0, 8/0, and 11/0, another has an additional cup for size 15/0. The larger sizes set has cups for 5mm, 6mm, 7mm and 8mm rounds.
The 3 inch has 2 variations. One has cups for seed bead size 6/0, 8/0 and 11/0, and one has cups for sizes 5mm, 6mm, 7mm and 8mm rounds.
Both sets also come with a lid and a solid bottom cup.
All the parts are 3D printed using PLA, (a bioplastic,) and can be customized on request! I can make these sifters for almost any size bead.
Sifters will be printed on demand, and each set of 4 takes roughly 4-6 hours to print. Customization will add another day to processing time, so please keep this in mind while ordering!
