Pixel Hole Jig

This jig is designed to drill a consistent series of holes 41mm apart in 38x25mm mini trunking for making outlines for Christmas lights. If you print it upside down it doesn't require any supports. The only other part needed us a 9.5x15.9mm spring and a board to fasten it to.

To use, simply start the first hold an appropriate place, then move the freshly drilled hole over the spring loaded pin. Drill the next hole, push the pin down, move to the next position and repeat.
