So I couldn’t find a mount made for my Leupold RX-1300 range finder. Had some scrap aluminum sitting around, so I welded up a “C” channel and tapped it 1/4-20 for mini ball head. Then I got some thermo plastic that is moldable at low heat. Shaped it to cradle in the aluminum channel and formed it to the range finder. Stuck a 1” Velcro strap on it and it work very well. This range finder has a weird shape that has no flat of perpendicular sides. I haven't seen this so I thought it could help someone that is having the same problem I was. Enjoy.
