The build is pretty straight forward, all you need is to print all the parts out an add a clear visor to the front part.
Helmet is for an M sized head with space for about 1 cm of foam on the inside. Please test before printing and scale properly if it doesn't fit. I already made a build myself which can be found on my YouTube Channel: https://youtu.be/cxzVKPaj2lE
