Cat/Anminal litter box filter.

I designed this to sift and get more life out of the cat litter. I use an automated cleaner but it doesn't catch everything but I'm sure you could just make a few size filters to get rid of dust.. So this is to help prolong the life of the litter.

Use for bucket size opening of between 6"-8" diameter.

Print top and bottom with 3 walls
use test file print with 0 top layers 0 bottom layers, 3 walls. And go for a hex infill at about 17-25% infill. Let clean litter pass through it as desired on filter mesh size. Size is up to you. Do some experimenting. This will work for dirt too.
Look at assembly pic... glue, or plastic weld together.
Make a few, make allot.
