These bins were parametrically modeled in Fusion360. The user parameters can be changed to individually change the Length, Width, Height, wall thickness, and fillet sizes.
Bins of the same size will nest on top of each other very securely. In addition, boxes that are modeled at even fraction will stack inside of each other. For example, 2 bins that are 2"x2" will fit in 1 bin that is 4"x2", etc
The 2x2 Bin is the base size. With that file you can make any size bin you want by simply changing the user parameters (In fusion, under the Modify menu, at the bottom is "Change Parameters") However if you do not have fusion, I will post all the models individually.
I have included the fusion files for you to play with as well as STL's ready for your slicer.
I use supports to hold up the underside of the of the bins where the fillets level out. I personally use rafts but you don't need to if you don't want to use them
