U.FL-R-SMT-1(80)

"""AI-created STEP model of the Hirose U.FL-R-SMT-1(80) coaxial receptacle (simplified).

Dimensions from Hirose drawing EDC3-302540-86 and the U.FL series catalog p.12: housing 2.6 x 2.6 x 0.35,
mating shell dia 2.0 to 1.25 high, outer-contact tabs 3.0 overall, centre-contact tab 0.6 wide.
No Hirose CAD geometry is used (the Hirose 3D model licence forbids redistribution and modification).

Frame: millimetres, Z-up, seating plane / PCB top z = 0, X/Y = the KiCad footprint frame with Y mirrored
(KiCad footprints are Y-down, KiCad 3D models Y-up), so the footprint's (model) block needs no offset or rotation.
usage: python make_ufl_step.py out.step   (CadQuery 2.8)
