Plugins for parametric joints?

Last week I built a frame in timber, where the joints were quite hard to make, so I ended up drawing it in Rhino and 3D-printing.
The project turned put quite good, so I will try to make a gh-script to automate the process.
Before I start, I would like to know if somebody has come across a script like this before?
I found one from Parametric House i believe, where they are using multipipe, but this is not what I am looking for.
