Customizable 3-prong Telescope Center Dot Placer better for some mirrors.

thingiverse

Decided to create a separate file for this 3-arm version of my original 4-armed telescope center dotter. This is because one of my scopes is stuck partially to a holder with three arms, and I had to cut off an arm to make it work. arms= allows for four arms (use only three or four, or you'll get unusable results) Important values: mirror_diameter (in millimeters), center_dot_diameter (in millimeters), center_dot_hole_diameter (in millimeters) For reference, standard US Office Depot white hole reinforcement labels (about 3 dollars) are approximately 14.25 millimeters in diameter, or about nine-sixteenths of an inch.
