Description
I added a spring mechanism to Thing from the Adams family so he pounces if you try to take too much candy.
Printing
I printed Wristy_thing in PLA, with no supports, and 5% infill to keep it light. I don't have experience printing with TPU but that would give a better hand texture.
All other parts I printed in PETG for strength, although it probably wasn't necessary for the base and washers.
Print the Coil_spring and the Spring_axel in PETG at 100% concentric infill.
Print the other mechanical parts such as the leavers, ratchet and ratchet blocker with 15-30% infill for strength.
All parts except the Ball_joint_socket, (L + R), and the Ball (L + R), print well without supports.
Hardware
Use 9 m4 x 10mm (longer for the thick Base) screws with a chamfered head to assemble the parts onto the Base.
Assembly
See the video below for most of the assembly.
I failed to film when I put the ball joint parts together, and I struggled to get them back out of the hand. To assemble that part:
Remove the supports from the Ball (L+R) and Ball_joint_socket (L+R).
Then put the ball parts into the round hole on either side of the Wrist_lever.
Put the Ball_joint_socket (L+R) around the Ball, and then push the whole assembly into the socket on the hand. It's a bit fiddly but it will go in.
Note, I found the ball joint to be looser than helpful. The Wrist would spin round the wrong way. I didn't dare make the tolerance any tighter, so my solution was to put something sticky/gooey in it (contact cement in my case), to stiffen it up a bit.
The additional holes on the top of the base are there to screw the mechanism onto a block of wood or other support next to your candy bole. The holes on the top of the axel stands are there to help if you want to attach something to hide the mechanism from your unsuspecting Trick-or-treaters.
