Optimized Storage for Harbor Freight US General Mini Toolbox

30% less material, 30% more space. If you use these custom grids with the custom bins I have modified you will get maximum storage space out of your mini toolbox. Bins for top and middle drawer are 20mm in height. The bins for the bottom are 35mm in height. For the middle drawer you will need one bin that has the cutout for the magnet pin that protrudes into the drawer. The middle slot will need the cutout bin only. Below is a picture of a regular gridfinity bin vs modified bin. I have a bunch of options that should have you covered for whatever layout you might want. If not, let me know, or use provided step files to create whatever you need.  -Cheers-

*Grids are backwards compatible with all gridfinity bins. The custom bins are not, and will only work with this grid layout.

Modified Grids to accompany custom deeper bins.
