I liked the original stackable box as designed by Nathan Kemp, but wanted to enlarge the divided sections a bit in order to store larger parts and tools. The lid, handle, and clips will all be identical to the design at https://www.printables.com/model/1204967-stackable-box.
I resized this slightly in Orcaslicer before printing (to 99.7%) in order to fit the build plate of an AD5M. M3x40mm screws fit for the hinges and clips. M3x25mm for the handle.
The author remixed this model.
This remix is an adjustment of the dividers - to change from 8 slots on the bottom and insert to either 2 slots or 4 slots.
