+## Flat_hinge
+A parametric flat hinge. A piece of filament can be used for the hinge pin.
+
+The width, depth, thickness, number and type of screws, number of knuckles, knuckle diameter, pin diameter and clearance can all be varied.
+A margin between the screws and the knuckle edge can be enforced to allow the hinge to bend all the way back to 270&deg; from closed.
+
+Opening the test in OpenSCAD with its customiser enabled allows these parameters to be played with.
+
+Note setting ```thickness1``` or ```thickness2``` to zero in the ```hinge_fastened_assembly()``` removes the screws from one side or the other and
+setting ```show_hinge``` to false removes the hinge.
+This allows the hinges and one set of screws to belong to one assembly and the other set of screws to another assembly.
