These are parametric vase mode Gridfinity bins. I exported a few sizes as .stl, but you can adjust dimensions and height in the Fusion 360 file. Just change the user parameters Num_X, Num_Y and Height. In order to print the foot in vase mode, which normally wouldn't be possible, you need to change the bottom layer number to 29 at a layer height of 0.2 mm in PrusaSlicer (see screenshot). I did NOT test this in any other slicer, so I can't tell you if this works. You may also need to adjust the wall thickness if you are using a different extrusion width. I have not tested it with very wide extrusions.
Edit:
I improved the design somewhat and uploaded a bunch of different sizes. The stl files are all 0.75mm wall thickness, which I can easily print using a standard 0.4mm nozzle. 0.75mm gives a good compromise of stability and material savings.
