Nesting Sifter Trays

 - - - UPDATE 12FEB2023 - - -

I re-uploaded the original 0.06", 0.09", 0.12" and 0.15" hole sifter trays after centering the holes in the bottom.  I know it's petty, but I feel better now knowing the holes are centered on the bottom of the tray. 

I also made improvements to the pour tray.  I made the walls higher on the spout side, since they were too short in the first iteration.  I appended the original pour tray name with a -001 and the new pour tray has -002 at the end of the filename.

I also added additional trays with 0.20", 0.25", 0.30", 0.35", 0.40", 0.45" and 0.50" holes.

This is a set of nesting sifter trays I designed for sifting play sand so I can use specific sizes of sand and aggregate for some epoxy casting projects without having to go out and buy the different grades of sand and aggregate - only to re-mix them.

These may require a raft to ensure that the hole size is consistent. If your bed is not perfectly flat and leveled, you could get holes that are smaller than desired. My 0.060" hole sifter tray had holes that ranged from 0.060 down to approximately 0.030". I did it the hard way and used an 0.063" drill bit and cleaned out every one of the 2,209 holes. It took a couple of evenings watching TV and running the bit through the holes.

Each one is approximately 6.4" x 6.4" x 1.3"

Edit: Added a tray so you can turn each sifter over and knock out all the aggregate and pour it into a container.
