This is all you need to print to make a cheap yet powerfull third hand helper.
To make your third hand you only need to buy on your favorite websote or shop:
- some "cnc plastic pipes"
- some "crocodile clips"
The ball intended to fit in the plastic pipes have to be printed with 0.1 mm slices, also it is a oog thing if you could print them fully-filled.
Top and bottom part and designed to be joined with 2.5 mm screws.
Fill the bottom part with any heavy things you have to have better stability.
If you want to update it to fit your tastes i gave you the source .scad file.
It is a good thing to print the balls in fully-filed
