I tried printing the original version of this helmet, but the jigsaw puzzle assembly was cut strangely with open surfaces. This was too difficult to print and was a nightmare during assembly. The pieces didn’t fit well so I did a remix of the full helmet.
I took the full build and sliced it into rings. These printed better without lifting and assembled easier. Also added 2 missing pins for the antenna hinge from the original make. I printed the model at 95% of the original scaling for better fitment. (I wear a size large motorcycle helmet).
Recommended print scaling of STL files:
-Main Helmet p1-5: 9.5%
-Pins (hinge and limiter): 100%
-All other accessories: 95%
You may want to scale differently, but recommend staying 10:1 accessories to main helmet.
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!
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 code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
