This template will help you align and drill the necessary 3 holes for a Euro Concealed Hinge.
Use 50% infill and 3 top, bottom and vertical layers.
Mark door for hinge centerline on inside face or edge of door.
Align with "V" notch. Use brad or screws to hold in place or go commando and just drill. You will have to figure out your own depth stop.
Do not drill through! 35mm (1/38") cup hole and screw holes should be 12mm (15/32") deep.
