Category for near miss constructions (where the actual length of some of the rods should be slightly longer or shorter, or the polyhedra are distorted).

The key thing about a near miss is that the level of distortion should be small enough that a Geomag model can absorb it: there are more formal measures of the distortion here: http://web.ukonline.co.uk/polyhedra/acrohedra/nearmiss/jsmn.htm
