This is my design of the 1970's Buck Rogers helmet. I have also included a file for the stickers (full scale) in the list of pics. The parts are for one side of the helmet so you will need to print 1 of each then mirror all the parts and print again. Helmet is large like the TV show, because they looked to have about 1" or more padding. I heard they were original motorcycle helmets. You will need to scale up or down if you want to change the size. I have shown a pic with the horizontal measurement. I also reinforced the inside with fiberglass strips on all the joints when I finished assembling it.
