Hi, did you have any luck creating a 3d printed attachment for the ipolar?
I'm thinking about doing the same. I've been looking at some placement options first. What's everyone's thoughts about attaching the ipolar to the side of the vertical arm? By using some type of clamp you could then ensure that the ipolar is correctly aligned (flat and square to the arm) and it is relatively close to the RA center - see attached (very) rough sketch?
I don't think the design itself needs to be that complex.
