Assembly Points

• Rotors, Gear Train Set and Casings can be assembled and adjusted separately.
• Combustion Air Casing is slid to the outlet elbow assembly until aft end clears from the turbine case its bore at first. Then slide back to bore. Gluing is optional.
• Standard Skill (such as Drilling, Tapping, Filing, Tightening, Painting and Gluing etc) is needed and perseverance too.

Total Net Print Time: Approx. 50 HR

• (Estimated as case of PLA, 0.4mm Nozzle, 0.2mm Layer Height, 40% infill and No raft and support)
  Note: When at actual print, each parameter may be adjusted.
