Mudtrooper - Large Helmet Buckle or Greeble

thingiverse

This is a modified version of the mudtrooper goggle strap buckle created by Vahlok. I've added a slight angle to both the front and back sections of the buckle to ensure a snugger fit around the helmet's curves. As a result, you'll need to print it in an upright position, but this adjustment should yield a more precise final product.
