Gear Iris v0.3

thingiverse

My gear-driven iris box prototype features opening and closing functionality via servo control. Despite its rough finish, this model operates effectively mechanically. As it's open-source, others can build upon my design. I used hexagonal nut traps in my design, but they are ineffective; the base is also thicker than necessary. I employed Greg Frost's gear scripts (http://www.thingiverse.com/thing:3575) for creating gears. Crucial insights include requiring a radius on small gears to define iris size, and ensuring that outer gear tooth count is a multiple of 5 for blade duplication and interchangeability. The model also features space for a sixth axis, which, when paired with one of the blades' gears, can drive the entire box using a servo (yet untested).
