Parametric gridfinity socket holder
Got tired of hunting down different socket trays to find them "almost" right for me, so I made one that uses the OpenSCAD gridfinity-rebuilt library, and generates a tray on the fly using a bin title, socket names, socket diameters, height, and orientation (and some fudge factors to get things where they look best). The layers on top are for the labels, so if you want to swap filament colors there, it's a convenient place do it.
There are several example sets of parameters in the file.
It requires you set the options for your particular baseplate, and manually size the grid base.
