This is a non-functional model quadcopter I designed. The body and rotor blades should be printed separately and glued together.

Dimensions:

Body:

Diagonal wingspan: ~173 mm
Body Length: ~74 mm
Body Width (at thickest point): ~48.7 mm
Mass (assuming ABS -- mass will vary): 33.5g

Rotor blades:

Span: 70mm
Central Diameter: 4.5mm
Mass(assuming ABS -- mass will vary): .4g

I created this model using SolidWorks.

Print separately and glue together.
