Khay phân loại đai ốc mét tương thích Gridfinity

Quickly separate and sort your metric hex nuts using this set of stackable trays.  The set is even Gridfinity compatible!

This design uses angled slots to allow the hex nuts to fall through  faster and with less shaking than using circular holes.

How to Use:

1. Stack the trays with smallest sizes on the bottom, and largest on top.
2. Add your mess of unsorted hex nuts to the top tray.
3. Shake the tray lightly to allow the nuts to fall through the slots.
4. Collect the sorted nuts!  Each tray will contain hex nuts matching the embossed size on the tray (i.e. M3 tray will only contain M3 nuts)
