Ball vise

Here at Thingiverse we found a similar device but I wanted to make mine with some things that I believe will make it easier to print and handle.

I believe the tolerance between the parts is in line with my machine's configuration and calibration. If you have difficulty with the master screw threading, please use the horizontal size compensation of your preferred slicer.

As a reference the ball is 100mm in diameter but I was also able to make one on a smaller scale with 70% of the original size.

The filling of the ball you can put iron filings or other heavy thing equally

Happy 3d printing!
