Hi, so I though too (disclaimer in the last sentence in the description), but that's okay, it is still a proof of concept and I'm still in the design phase for printable ball joints so I can correct that :-) THank you once again for the inspiration!

I'm pretty sure this bicep is not going to work. By changing the thickness of the bicep you've moved the location of the ball joints and that will alter the math in the software. In other words, now that the bicep is thinner the tool will not go where you expect.

Instructions

Inspired by i-make-robots delta robot I continued my stalled project I started long time ago, before the days of my 3d printer....

I haven't completed it but saw the potential to improve the design of bicepts a little bit

This version of the "Biceps" to a Delta Robot have the pocket for the servo arm on the other side than the original making it possible to mount without a glue gun. Actually I didn't even needed a screw to hold it tight, at least when the robot had no movements.

This "thing" is 6mm thick at most places, and the pocket for servo arm is 2mm, making the middle bit of the servo arm beeing ~1mm below the surface in order to get the screw to tightly secure the biceps to the servo. (i printed the first version beeing inline but that wasn't good enough)

As I haven't finished the design/build of the robot I don't know if there is need to extend to cylinder some more to have it in the center of gravity of the robot, but as I plan to have a screw there to mount the joints on I can easily add an extra nut as distance I presume.
