The CAD parametrics for this fuselage can set to a wide range of sizes for width and height. This version is 124 wide and 45 mm tall. This size is a good compromise for small size and usable interior space.
Larger and smaller sizes are possible and will be published depending on interest and requests. The arms may have to be increased in size if the body is significantly enlarged.

Suggested Infill Settings
Infill depends on the length of the arms and the size of the motors. For short arms and small motors you might consider infill from 15% to 25%. For longer arms and larger motors you might consider infill from 30% to 50%.
Suggested Supports
Supports may be necessary for the inside top lip and some of the holes in the body sides. You may wish to experiment with few or no supports and add them as needed.
