Rocketdyne Classic Logo

This is the original 1950s Rocketdyne logo, from the company that made the F-1 Rocket engine that powered the Saturn V (here is a printable one!)

Somewhat tricky to print due to the sharp corners, you may need to tweak your extrusion widths to get good results.

Update 2017/03/16: added a recessed dualstrusion model (with the logo flush to the top surface of the base).

The SVG file is also included. Be careful if you extrude this for use in a 3D model: the top triangle will probably cause the model to be non-manifold. I solved this in the STL by detaching the triangle and shifting it upwards a fraction of a millimeter.
