I tried another variation of the helmet bolts but I don't think my FDM 3D printed can do it justice, so I reached out to Imperial Surplus to get a set of the accurate bolts. For the boots, I added notches where the tread occurred on the boots, please let me know what you think (I'll clean up the grey overpaint soon):
I also got a better suit up, I think it's looking pretty much there. I can do the belt and cod a little bit higher and the boxes a little bit wider next time.
