SCOPE AND LIMITS (read this before relying on the part)
  STL and STEP carry geometry only. Material (mild steel) is a
  declaration in the prompt and this report, not embedded in the
  files. Clearance is ISO 273 medium fit for M12. No tolerances
  or surface finish are modelled. A qualified engineer reviews
  and signs off before anything is fabricated.
