Hinge Variations

Reusable parameterized hinges. The hinges are designed with an additive and a subtractive part, making it easy to combine with other design elements. This is the same hinge design I used on my Pop Box (http://www.thingiverse.com/thing:248387). The file hingePairBase.scad is the main design file. All the other SCAD files are small variations from the base and are named with the parameter they tweak. Modify the SCAD to suit. When using the hinges, bear in mind that the hinge has a top and a bottom. Keep the plate material on the left to ensure that the subtractive parts are correctly oriented. For example, this means that if you were to lay the hinges around a polygon, one per side, you would need to make them go bottom to top in an anticlockwise direction to keep the polygon material on the left. The pin for the hinges is filament. Try various filaments you have to find which one works best for the inside diameter you print with. I find that my glow in the dark PLA fits well in a 2.06mm inside diameter hole, but red ABS needs to be sanded down slightly. The hinge sides with the lower hingelet count are made slighly larger than those with a higher hingelet count. This is make one side grip and one side rotate smoothly. I printed all of these in PLA at 0.2mm layer height on a Replicator 1.”
