I designed this model based on a metal holder that we had for minerals. It has an internal diameter of approximately 77mm and the rod ends are approximately 10mm which means you can clamp anything that is <~57mm or less.
You will need to print the following items:
1 x Arch
2 x Rod
2 x Rod End
1 x Stand Rod
1 x Stand Base
The tolerances on the screws are very tight. For that reason, I recommend scaling the X and Y for the rods to fit into the other pieces. For me, a 95% scale was a loose fit.
No supports needed
Recommend printing with 0.2mm resolution or finer for the threads
Infill should not be an issue.
