3.5 inch circular marking templates

thingiverse

Need to mark evenly spaced holes, each 3.5 inches in diameter? Ditch the protractor and use a template instead. This tool comes in two flavors: an 8-hole version and a 6-hole model. A crosshair is cleverly placed at the center to guarantee everything remains perfectly aligned and level. The holes themselves are intentionally designed to be small, ideal for use with a small scratch awl - but can easily be enlarged if needed.
