Summary

Gridfinity Divided Plain Bins. It doesn't really use the proper "unit system" for the height, it is plainly stated in filename and measured from the top of the solid base level to the top of the rim.

My base is about 7mm thick.

So if it says half inch, it means the storage area is 1/2 inch tall. Measured from the top of the solid base level to the top of the rim.

I wanted a flat base floor, so that is why I designed it like this.

Comes in some various sizes Idk how to make this parametric but there are a lot of useful ones premade.
