Parametric hinged and bolted attachment for square bars

This OpenSCAD script will generate a 2 part holder to attach a Tyndall WIMUv3 to the upright square cross-sectional posts on the moveable sled part of the assassin trainer at Bath University. The size of the bar it is attached to can be parametrically varied
