Brass Sorting Trays

A set of stackable brass sorting trays to separate your range pickup by caliber.

Choose the size that best fits your needs.  Small is 150mm, Medium is 175mm, Large is 200mm, so any size should fit on a 220x220 build plate.  Pictures are medium.


Sizes range from 8-12 mm in half MM increments.  Choose the trays you need based on what you want to capture.  For example a 9mm case is 10.01mm in diameter at it's widest point so so anything less than that will catch it.  Note that 10mm catches it for me but we're talking 1/100th of a mm here so YMMV.

I use:

10mm to catch 9mm
10.5mm to catch 40 S&W and 357 SIG
11.5mm to catch 45 Auto

I could put an 8mm in there to catch 223 Remington and 300 AAC Blackout but genrally these are easy to pick out from others that fall through.

Anything smaller than your smallest plate will fall through to the base (if used).

I printed with:

•  0.20 line height
• 10 wall loops (this ensures the grid pattern is all wall to keep it from flexing and allowing cases through that shouldn't go
• Brim on outside only

Use scarf joints if you want to minimize seams, though I left enought of an offset in the stacking that they work fine without.
