Divider for Harbor Freight 24-bin Benchtop Parts Rack

If you've purchased the 24-bin Benchtop Parts Rack from Harbor Freight, you may have noticed that each bin has slots/holes for up to three dividers, but it doesn't come with any.  It's a pretty nice organizer even without dividers, but with them, it's awesome.

I hate having dividers move or come out of organizers so that everything mixes together--what was the point sorting it at all?  So I designed this to fit snugly into the holes/tracks along the top of the bin and the ridges along the bottom.  If the sides of your bin have bowed inward like mine, you will likely need to hold them apart while you position the divider, and it will probably require a bit of force to fully seat it, but once seated properly, it won't come out!  There are two versions: one has a dimple on the bottom to accommodate the bump on the floor of the bin in the center position, and one with a flat bottom for everything else. 

I printed mine with the cheapest filament I had--some Kingroon white PLA--with a .40 nozzle, a .20 layer height, and 15% gyroid fill, and they worked great.  No need for brims or supports--just lay it flat on the build plate.

Hope these help to fill a hole (pun intended!)
