Ram Mount compatible double 1"ball (B Size)

This is a double B Size RAM mount ball for adding two clamps to give more movement.
It is strengthened with the addition of an M6 countersunk head bolt and nut that runs down the centre.
I printed at .1mm resolution without support and the balls laying on the small flats.
To finish off and add grip, the balls were painted with a thin layer of liquid electrical tape. you could also smear a very thin coating of silicone or similar.
