Print-In-Place Pantograph Copier
A four-bar parallelogram pantograph that prints fully assembled in one piece — four bars on captive pin joints, no fasteners to add. Trace an original with an 8 mm stylus in the tracer socket and a pen in the output socket draws it at exactly 2:1 scale; both 8.3 mm sockets take an 8 mm rod or pen barrel and have M3 self-tapping pinch screws. The fulcrum eye takes an M4 screw to anchor it to the bench. Overall 169 x 68 x 19 mm.
