Self-centring dowelling jig for 18 mm board

Drill centred dowel holes in board edges

Drop the jig over the edge of 18 mm board: the two fences straddle it, so the guide holes sit dead centre on the edge, 32 mm apart, and the double guide plates keep an 8 mm bit square. Drill both parts from their face side and the dowels line up every time. Print it as shown, then turn it over so the floor becomes the top.
