This is specifically designed for these bath color tablets found on amazon. They're the best colored bath tablets I've found for kids.

I got tired of hand sorting the smaller tablets from the bigger tablets so I made my own way to filter them! Simply print, place, and shake for 5 seconds and all the small tablets will filter through into the container below. This is my first design I've done with threads so I'm not sure if there are better ways to do it, but the device works great.

Prints with no supports.
