These are Gridfinity bins for the Irwin 3/8" Forstner drill bit set of Imperial sizes.  The set is advertised as "14 sizes" but it's really 13 sizes with the 1/4" bit duplicated (huh?). 

The fraction labels on my smaller tray didn't turn out well when I printed mine, so the published model has the font size one step bigger in the hopes of making them more legible.  If you don't reslice the .3mf, you'll get the color changes.  I made the bins stackable both for space savings as well as a guard against accidentally brushing the cutting edges. 

Printed in PETG with 10% infill.
