Hi all, I'm building one of these printbot rhino vehicles:
http://www.thingiverse.com/thing:288663 and I'm having some issues trying to find a disc shaped server horn for the Parallax servos I'm using. Of course, my servos came with star-shaped horns but nothing else, and I'm having a heck of a time trying to find the right model. Listings on Ebay and the like don't tend to give specific dimensions of the horn or its "spindle", but I imagine there's got to be some standard way of specifying what it is I'm looking for. Here's the servo I'm using: http://www.parallax.com/product/900-00008 What I need is a 20mm diameter disc-shaped horn. I thought I'd be clever and buy a couple of these: http://www.amazon.com/Hitec-31311S-HS-311-Standard-Universal/dp/B0006O3WVE/ref=sr_1_1?ie=UTF8&qid=1415383107&sr=8-1 and then have a couple of spare (non-continuous rotation) servos to play with and could use the horns, but it's not the case. Not only is the disc horn that comes with that 24mm in diameter, but the inner threads don't even match with the teeth from the Parallax servo. These are the only parts left I'm missing for this robot, can anyone suggest what I should try next?
