Grid Fin - SpaceX Falcon 9

My Replica design of the transsonic Grid Fin from the SpaceX Falcon 9 first stage booster!

Hi, I'm the original designer!

This is a mini passion project of mine– I was just so impressed by the complex geometry and design on this enormous part I had to design it from scratch. The full size one is the largest cast titanium part on earth and is rumored to cost over a million dollars each! Print yours, paint it, and put it on your wall to help steer your imagination at supersonic speed

Having trouble with your print? Want some tips or to talk shop? Need a variation? Help or advice? Message me on discord/telegram!

Designed it in OnShape so anyone can fork, extend, configure, and download any version of it they want just in the browser. Used some of my favorite advanced CAD techniques like sweeps along 3D projected curves, extrusions to complex lofted surfaces, and large boolean subtractions. Should be configurable to any size while independently specifying the wall thickness allowing perfect 3D prints.

See my printables page for a few more size/mount options!

Print one? Post a 'Make'!

I'd really love to see how yours comes out!

Make one for your wall, one for your friend, one for your model rocket.. then post the photos!

Printing

Print it as the STL is oriented, standing up on end. Prints without supports. Small ones can be printed in less than an hour, mymax version took me 23h to print on my old Ender 5 in HTPLA+ from Fusion Filaments with 1 perimeter and 18% infill.

Wall mount

You can also mount it on your wall with the optional pivot-arm and keep space history as art!
