R2D2 Dome Pie Panel Hinge

This is a design for a pie panel dome hinge to suit [Michael Baddeley's V2 R2D2 dome](https://www.patreon.com/mrbaddeley/). This is my first 3D design, so I am still learning as I go.

I have included a modified pie panel with a flat spot and screw holes to attach the hinge, and modeled in details.

The current version of the design suits 9g servos such as the Turnigy TG9e or Hextronik HXT900.
