This visor is based on the Uncanny X-Men from my childhood. It's for my 5 year old son, so I scaled an adult version down to 90%.
I don't have much luck printing big, curvy objects on top of support structures, but the halved version printed well for me. I'm still new to this!
Like the previous one, I made room for lighting and a coin battery pack/driver. Mine uses EL Wire and a "micro EL driver" found easily on eBay.
