Divides the excellent and cheap ($3) STOREHOUSE 4 inch stacking and tilt bins avaialble from Harbor Freight into 3 compartments.

Useful if you have smaller quantities of a part and don't want to waste all the space of a whole 4 inch cube

These are the specific bins that work with my divider

If you have a Bambu Lab machine, I suggest using my provided 3MF profile as I did a lot of tweaking to make it ready to go. But STL is also provided if you want to slice your own.

There is supports and although they come of cleanly, you'll need something thin and metal to pry away the support from the bottom like I showed in one of the photos. Once you get that started, the whole support comes off in pretty much one sheet. The support is needed because the bottom of the bins have a recess that this divider uses to “lock into” to help keep the divider secure.
