No way to tripod mount your particular binoculars or telescope? This version is for heavier binoculars which need a little extra support, but will still work just fine with smaller, lightweight binoculars.
Simply take the measurements shown in the attached image, and plug them into the "barrel_diameter" and "arm_length" variables. Print, add a 1/4" 20 thread nut, and you're good to go!
Note: You may want to go a little long on the "arm_length" for aesthetic purposes.
Print in the default rotation for best shear strength.
You may or may not need supports for the hole in which the nut will be placed, but it might be a good idea to generate supports just to make sure the hole keeps its shape, enabling the nut to fit properly.
I tried printing with no supports, and it actually worked fine. The hexagonal space for the nut was a bit tight, so I heated my nut on the stove and pushed it into the hole, where it fits nice and tight.
