I designed these to work with the old blue Akro-Mils parts organizers, but they can easily be modified for other drawer sizes. (Onshape link here)
They are meant to be printed in vase mode, which helps to not waste filament, improves surface finish, and makes them print out VERY FAST.
Note:
If you're looking for these exact Akro-Mils parts organizers, I've found them at antique stores, estate sales, and they are usually found on Ebay for reasonable price.
The author marked this model as their own original creation.
