This is a remix of Dr_Lizardo's creation made to fit the 15-Compartment Interlocking Small Parts Organizer from Home Depot. It looks like it'd fit the WalMart Hyper Tough Version as well.
This print has to be pretty precise. It fit well when I printed it in ABS, but was a little loose when I printed it in PLA. You may want to play with the scaling a little if your first print doesn't fit quite right. It is designed to be printed on its side without supports.
The compartment (bins? splitters? things?) shown in the picture that allow for organizing smaller parts are a design of mine as well. I'll post them just as soon as I clean up the .scad code and come up with a name for them.
Huge thanks to Dr_lizardo for the great idea!
