Gridfinity Extended aims to be the most comprehensive OpenSCAD implementation of Gridfinity.
It is opensource and maintained by myself on GitHub here ostat/gridfinity_openscad .
This scrips are actively maintained, and have regular improvements.
If you have issues or suggestion submit them on the GitHub page.
Print profiles
I have generated a set of Basic Cups and attached print profiles for them for easy printing.
The matching STL models are included in an attached zip file.
