A jig for the diagonal rods

When calibrating a linear delta 3d Printer it is essential to have all diagonal rods the same length, or at least within close tolerance. The easiest way to achieve this is to assemble the diagonal rods on a jig.

I decided to reuse some of the OpenSCAD code from my earlier Traxxas 5347 ball link assembly tool to design and print the couple of jig posts required for the jig. Then it is just a matter of gluing the posts on a flat surface with one of the rods assembled on it, and then assembling the other five remaining rods on the jig.

By "assembling" I mean just mixing some epoxy glue and gluing the Traxxas connectors and the carbon fiber rods with the printed joiners on the jig, while making sure the Traxxas connectors are on the same plane.

Diagonal rods: done! Their measured length is 372mm.
