OK, I've completed the testing, tweaked the design and written the instructions. The Gripper Arm is now ready for you to print, play and test :-) As always this will be released to the lovely early adopters through the Patreon Share, I'll move it over to the public folder in a couple of weeks once we've all tested it. Thank you again for all your support, I'm particularly excited about this one as it "does" stuff. I've added the modified Padawan code to the Patreon Share also in the Gripper folder. I'm not a programmer but I've added some notes at the end of the instructions and included the code to keep you going whilst I write up some better notes. Happy Printing, Mike.
