OpenSCAD library for generating extrusion t-nuts of variable lengths and holes. Preconfigured for M3 sizing with examples, and includes four pre-rendered STLs (10mm, 20mm, 40mm with 20mm spacing and 60mm with 40mm spacing).
Now includes parameters for setting the type of nut (nutsides=4 and nutrotation=45 for square nuts)!
