Rock/Mineral Holder

thingiverse

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.
