Drew up a little flashlight clamp to mount my red flashlight to scope for hunting coyotes. Both diameters of the clamp are set up for a 1" tube. A 1/4 x 20 bolt is used to join the pieces and I added a cap to the bolt to allow adjustment without tools. The one side is recessed to house the 1/4 x 20 nut. I may build up the bolt side so a spacer is not needed with the cap but this works for now. I printed with supports but you probably don't need them (makerware only added support in the center of the through holes.
The scope clears my 40mm objective but I haven't tried it on the 50mm. I may have to make the entire assembly longer if it is an issue.
