Parametric bin and grid, with x, y, and u.
The stacking lip has notches to prevent sliding of stacked boxes
No magnets.
Recommended way of using it:
For the grid, just use as-is. Open the file, edit x and y, and export to your favorite file format/slicer.
For the bin, I've been importing the component into other fusion projects, and then breaking the component link. That allows me to edit x, y, and u, and then I can customize the inside shape of the bin as needed. By default it's a fairly simply extrusion cut from the top down, but that gives fairly thick walls and a thick bottom. It works alright though, but you could customize it for specific things by suppressing the last extrusion in the bin component.
The notches on the stacking lip should be fully compatible with all other gridfinity bins. I got annoyed at the sliding that happened when you stack a 2x1 bin on top of a 2x4 bin for example. The notches prevent this, they essentially follow the spec for the grid, adapted for the lip.
If you want to remove the lip entirely, suppress/remove every operation after the first rectangular pattern.
If you want to add in magnets, I'd recommend doing it before the first rectangular pattern operation, and then include your feature in the rectangular pattern.
I tried to keep the fusion360 operations straightforward and error-resistant, so it works from x=1, y=1, u=1 up to whatever size print bed you have. For ‘u’ you can also use decimals, if you happen to need u=5.3 for example. The operations have names describing roughly what they are for.
I've followed https://www.printables.com/model/417152-gridfinity-specification for the specs.
