A door hinge with integrated stop. Based on the architectural symbol for a standard door.
Masters of all three parts (hinge pin, door plate, wall plate) are produced via a rapid prototyping technology). They are then cast in bronze (wall plate) and brass (hinge pin & door plate).
Closed, the hinge is 8.3cm across. The hinge pin is 13.4cm long. Installed, the hinge projects 5.35cm from the door surface.
This version of the stop allows the door to open no more than 90 degrees, but the design is easily modified (before the rp process) to create any maximum opening. This ease of customization / adjustment (and being able to visualize the results pre-production) is one of the benefits of working in the CAD environment.
