This gridfinity sorting tray lets you sort that catch-all overflowing with random screws and nuts and whatnot directly into their bins!  No need to precariously tip or dump: slide them directly into their final receptacles.  If you don't like having four holes, you can cover any with lids before sorting; or put that fancy 1x1 screw measuring tool there.

Fully gridded top and bottom (2u high), so you can store it on your existing base under your bins and keep the parts right on top.  You can span the center tray with anything bigger than 1x1 – if you really must put 1x1s there, check the bonus frame!

Only about 30m of filament (90g PLA) at 15% infill.  Great for beads, m2-m5 stuff, small electronic components, etc.

(Why are there marbles etc in with my parts?  My kids got to do the sorting…)
