Folding Third Hand / Helping Hand

thingiverse

This FoldingThird Hand / Helping Hand rig was inspired by Digitalworks version https://www.thingiverse.com/thing:4505874 of his remix of Crysis_ps version https://www.thingiverse.com/thing:1120068. The Forearm is my original design and more information can be found at: https://www.thingiverse.com/thing:5245945 This Make is assembled with imperial hardware (#6-32) although M4 hardware may still work depending on the accuracy of your printer. Since the original Thing and the Remix did not provide any files to allow modifications, I had to model all the components again. I added my own 'flair' as I went along. And, I reused parts from the original Thing for the Arm and Hands. The Base is designed with tabs so this assembly can be mounted to a heavy base - to keep from moving. The Base is attached to the Body with a 1-1/2" long pan head screw and hex nut. The Body is designed with the Cap in front (like the original version) for better aesthetics. The Cap is held in place with (4) 1/2" long pan head screws and hex nuts. The Arm and Hand components are reused as is. I used #6-32 Socket Head Cap Screws and Button Head Cap Screws from my parts bins for attachments. There is a washer and wing nut at each joint to lock them in their desired location. The Axle (or Rod) is 3/8" diameter and approximately 6" long. (Again, from my parts bin.)
