Glass ball holder

This is a simple holder for a glass ball I was offered but I was unable to put it anywhere because there was no support to hold it in place. 

You can stick rubber pads below the model to keep it in place while manipulating the glass ball or use double sided tape to stick the ball to the holder.

The glass ball diameter it can fit is 80mm, you can make your own version if you modify the Onshape model available below.

The CAD model from Onshape is available here

As always with my models feel free to copy and modify it.

The Onshape model is not fully parametric, sorry I'm often a bit lazy with 3D modeling.
