K'Nex parts, customizable Remix

thingiverse

All credit goes to coolsa for this incredible Openscad parametric design. I've added more parameters to fine-tune the fit of connectors, addressing a major issue I faced with the original dimensions: they were too loose when connecting to rod sides, allowing parts to slide around. This wasn't ideal and didn't match my recollection of how K'Nex worked. Since I don't have actual K'Nex pieces, please let me know if the default settings need adjusting. As it stands, the defaults work great on my CR-10 printer at a height of 0.28mm and width of 0.56mm. However, there's still an issue with part 3 (rod) - it's not manifold, and I'm unsure why this is happening yet.
