10mm Barrel Hinge centering jig

This is a centering jig for 10 mm barrel hinges to achieve a good alignment between the top and bottom half of a box. It will mark the opposite side using a brad nail located in the center. I used these 10 mm barrel hinges: https://www.amazon.com/gp/product/B073JDD4KZ/ref=as_li_ss_tl?ie=UTF8&psc=1&linkCode=sl1&tag=restrictedaye-20&linkId=cf2c77781a0b6c719a90ed0d65d502c1&language=en_US and a Fisch 10 mm Brad Point bit to drill the holes https://www.amazon.com/gp/product/B073JDD4KZ/ref=as_li_ss_tl?ie=UTF8&psc=1&linkCode=sl1&tag=restrictedaye-20&linkId=cf2c77781a0b6c719a90ed0d65d502c1&language=en_US

Print as many as needed for placing the hinges you need. Insert a brad nail through the center hole and place the jig (nail-side-up) into the pre-drilled 10 mm bottom half hole. Place your lid with the alignment desired and press down to mark precise locations as to where to drill top half holes.
