Cobra HISS (G.I. Joe)

<b>HEY STEVE'S TOYS: STOP SELLING MY WORK. I HAVE REPORTED YOU TO HASBRO.</B> I have printed almost all of Jabberwock's GI Joe models and I have a nice display down in my work room. He always says in his info that he modeled them at 100% toy size, but that we should print them at 25% for best results. This is all fine and good, except I want full size! I have a printer and what the hell, might as well. So I started with his HISS. So during CV-19 lock down, this is what I have been doing. I adapted his HISS and created working tank treads for it and I added all the details you'd expect in a full-sized toy. Along with working tank treads, I added the cockpit and windshield, tow hitch, and spot for a gunner inside the turret (which also turns). The stickers in my pictures were cut with a Cricket Cutting Printer. For printing it, I used eSun Black and Gray PLA+ the entire thing, except for the windshield, which I used eSun Clear. It's not clear, by any stretch of the imagination, but it is better than nothing. As for how to print it, you know your printer best. I used 0.2 layer height and I thought it came out great. I would have used 0.12 had my prototype parts looked less than great, so I just decided to save serious printing time with 0.2. As for supports, if it looks like it needs supports, it probably does. For the tank treads, it took <b>50 pieces</b> to make the belt for each side. Which means 100+ pegs. You should not need supports on those. I printed 25 per batch and had no real issues. On one of printers, I had to use a BRIM when printing the pegs, on the other, I did not. So again, you know your printer, do what it takes. They are designed to print laying down, so that should make it easier. There is a part called BLOCK. This is used to connect the 3 chassis pieces together. It is meant to help with alignment. I had to print the block a few times to get it to fit. 98% was the magic size.
