This Upload
This is a multi-color adaptation for a model I initially found on the https://www.printables.com website. I have cut the model to give the helmet a flat bottom surface for easier printing, supports are enabled and highly recommended for printing this file.
Model Origins
The files were originally uploaded by Jace1969 on https://www.thingiverse.com, then ported to https://www.printables.com. I would like to note that currently the true origin of these files is unknown/no longer available, as according to Jace1969.
