Easy to assemble, full size, and of course, wearable. Enjoy trooping!
You need a Creality3D CR-10 or an 30x30x30cm printer in order to print this helmet. 2.500.000 polys PLA 0.2 mm layer 210° - 50° Modified Chris Elkin's profil: 3 perimeters, 40mm/s last perimeter at 30% (you can go faster with an regular CR-10, I have a S5 and I must slow down to avoid ghosting). Printable with 1kg spool (all parts, including supports).
You need a SG90 servo for the rangefinder rotation, even if you don't want to add electronics and lights. If you want add functional lights, you will need two regular red LEDs and thin wire (I get it from an old cellphone charger). You can use an arduino nano to control the rotation of the rangefinder and lights. There's a pdf with the instructions for the electronics, but it's in spanish, sorry. I have not idea about arduino, so my brother did it for me. I can't answer questions about electronics, sorry.
You will need six small screws for the visor.
Includes the pattern for the visor.
INCLUDES SIMPLIFY3D SUPPORTS. Just load the object and import the supports for every part. Everything is allready rotated and ready to slice.
