3D Printed Rocket Fin Can #3DThursday #3DPrinting

Pasted Image 11 21 13 1 56 AM

A recent 3D printed hobby rocket experiment from someone working on the forefront of actual-space project SpaceX — check out more of Steve Jurvetson‘s photostream for examples of printed tests and launch photos. Pretty incredible!

3D Printed Rocket Fin Can – just epoxy to a blue tube and top it off with a golf ball nosecone.

The 3D print removes the vast majority of the labor (fin attachment and alignment). It also has integrated launch lugs and fillets as part of the print. More build photos below.

It can take single use aerotech H motors, duct taped at the rear for retention. The golf ball weight can be shed at apogee, allowing the airframe to come back with a streamer of DANGER tape (the hardware store sells rolls of this inexpensive plastic)….

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Join 9,700+ makers on Adafruit’s Discord channels and be part of the community!

What do you want from CircuitPython in 2019?

  1. it should be noted that Jurvetson is kind of a big deal. he is a venture capitalist and sits on the board for both SpaceX and Tesla. He is the world’s first Tesla Model S owner.

  2. Having fins that are printed as one piece would surely make them stronger than gluing on fins and hoping they stay on.
