This parametric spider coupling is a redo of Zignig's spider coupling ; written from scratch to prevent some manifold issues I was having with Zignig's version. Zignig's allows for multiple coupling legs while this simple scad is limited to dual leg layouts.

Both bore holes have individual sizes.

How do you attach them? I dont see holes for set screws (or the nut that would allow the set screw to work in plastic)

I always just increased the size of the base plate a bit, and jammed the coupler on top. Maybe a touch of glue. If you want to do it right, could increase the base thickness, and add a hole. My attempts to print screw holes as small as a set screw have always been ugly. I've just had better luck drilling a hole after printing. I can modify the SCAD if you like.
