Dual square for woodworking

I designed this dual square to help me in making furniture with 18mm laminate.  It features:

• left/right angle guides for 15, 22.5, 30 and 45 degrees;
• a measuring gauge for 5 to 40mm in 5mm increment;
• a 33.5 marking for the center of the 35mm concealed hinge, at 6mm from the edge;
• a 9mm lower lip for marking the middle of the 18mm board

It can be printed in PLA, ABS or PETG, at 0.2 resolution, without rafts, brim or supports.
