This is a high quality, full size model of the WWII US Army M1 helmet. This has 3 30.06 bullets modeled to the right side. This is modeled full size as there was only one size that was manufactured. I was able to print it on a BambuLab X1C at 94%. You have to position it so it sits flat on the bails (chin strap slots). You can split the model to objects if you want to remove the bullets.
