We needed a tool to turn the APU on a Boeing 787 Dreamliner for a boroscope inspection.

Due to the frequent unavailability of the tool and the high cost of renting it, I decided to make one.

Original part can be seen in green. Modelled part can be seen in Black ABS for high temperature resistance.

I modelled a 3/8 drive to connect a ratchet but the APU's turn so freely that it can be used by hand to turn the APU for inspection
