[QUOTE="Nosegoblin, post: 405353, member: 7983"] The first printer fell through but I was lucky enough to stumble on another 3d printer... very happy with it, so not the build begins! The long wait for the Kickstarter printer is over! My Raise3D N2Plus arrived in good condition. After a few small test prints to get the feel for the software, printer and materials I finished up the helmet and jumped right in. I settled on PETG as my build material, it has some flexibility and is very impact resistant. PETG can be a pain to print in and there are very few solvents that can be used to glue parts together, lucky for me, this is a monster sized printer. I needed to do a bit more work on the CAD model and shell the model for the proper wall thickness, I tried to keep it at about 1/4 inch thickness for strength. I removed the ears and mic. to print them separately, I made the ear sections hollow so that I could put some screening over some small detail holes to aid in hearing while the helmet is on. I may take apart some shooters ear muffs and put the electronics in to use as amplifiers.
