Print instructions

Category: Vehicles Print Settings

Printer: Rebel II

Rafts: No

Supports: No

Notes:

You need extra weight on the nose to make the model stable, so for the X-43A use enough infill.
I recommend to cut X-43A in half, print it in two pieces and bond.
Look into the Open Rocket design sheet for the stability calculations.

Not suitable for beginners.

How I Designed This

Construction tools used:
Solvespace V2.3 (elementary design),
Blender V2.78 (main object design),
3D Builder (.stl model fix),
Open Rocket (stability and fly simultaion)
