Cartwheel flexure pivot

Parametric cartwheel flexure pivot: a square outer frame and a central hub joined by three thin spoke blades that radiate toward the common centre — a monolithic, backlash-free rotary pivot whose axis is the virtual blade crossing. Set outer size, hub size, height, blade thickness and gap. Print as one part; the blades flex about the centre.
