This turned out so awesome! Congrats on the successful build, great photos too.
There's definitely more options for the LED arrangement than the two that I used. My recommendation would be to temporarily attach the controller to the collar, plug in the splitter and LED strips, and use painters tape to position the LEDs in different configurations. Turn on the lights and see how it looks. Then once you find one you like, permanently secure everything into the helmet. I don't recall the glare being too harsh with either placement though. The lights I used are dimmable which was a nice feature.Total materials cost was about $120 each. I already had the printer filament on hand though, so that doesn't include the cost of new spools.
I am honored! A huge thank you to the Instructables staff!
Not in the current configuration, but maybe you could rig it to backpack straps to help hold it on.

I think it would work great; the front headband and the elastic around the back should still hold everything securely.
Thank you so much!
LED Space Helmet - 2019 UpdateView Instructable »
Hi there! My apologies for any difficulties with the instructions. I found the inconsistency where the parts list said 2-gallon bucket, but the instructions said 5-gallon. So sorry! I'd be happy to chat about modifications that could be made to the collar and pivot designs that could adapt to the larger diameter hole in the sphere. Send me a message and we'll see what we can come up with!Best,Jenn
Hi Steve, great question! The 3D printed pivots are sized so that they bump the visor outwards just a bit. The flexibility of the acrylic also helps, allowing the visor to be widened by just enough to clear the top of the helmet. At NASA, though, I'm quite certain they manufacture their visors to have a slightly larger radius than the helmets.

Ah, I see! It should have said "The space helmet collar is actually the top edge of a 2-gallon bucket." The diameter is 9.5" which worked perfectly for these.
Good catch! The link has been updated.
Pivot files sent! For the 12" sphere, another maker had successfully completed a 12" helmet using the full-size pivots. The main difference was that only 3 of the 4 visor bolt holes were used. That being said, it would be interesting to see what would happen if the pivots were scaled to 86% (I think?) of original size to adjust for the size of the helmet.
I've printed some pivots in ABS and others in PLA, and each one worked great. They are designed to be on the robust side without needing to be printed with solid fill. I think as long as they are printed with a wall thickness of 3+ layers, they'll be good.
Hi there,Sure thing! What email address should I send them to? The email will come from me at email@example.com.Best,Jenn
Hi there, I'd be happy to send the files! What is your email?
This looks amazing! Congratulations on such a successful build. Love the idea of nesting the LEDs along the collar. Out of curiosity (an in case other makers would like to make one too), did the pivots scale directly for the smaller sphere, or did you need to make any changes to them?
This turned out sooooo awesome! Thank you for sharing it!
Excellent transformation of materials! The final result doesn't look at all like styrofoam, certainly looks like you got something straight out of Myst!
Thank you so much, Mikaela!
