So recently I have decided to try to design and make a 3d printed helmet for paintball. The problem is, I am still stuck on the design stage. I have tried numerous times to draw out the helmet, but I can never seem to figure out what tools are the best to use. I would appreciate anything you could help me with, but keep in mind that what I am looking for is mainly the paths that I could use for designing etc. Attached is a picture of the end goal helmet.
