Telescope Tube Rings for 60mm Refractor

Scope Tube Rings for mounting a 60mm Vixen f/9 scope (other scopes may also work) to a Vixen dovetail.
The telescope is a very tight fit, which means direction cannot be adjusted but it will also not exhibit differential flexure. It is necessary to tap the horizontal holes for M6.
Version 2: when tightening the horizontal bolt, the plastic tended to crack. Made things a bit thicker and got rid of the corner where the cracks occur. Also added a hex hole on the inside, so that you can put a nut in there and attach the bolt from the underside.
