I believe it is because some parts are not easy to be turned into a working costume. The Jesse M files has become the "go-to" files". The arms and torso on the outdated files do not have a way to be used for a working costume easily because some of the parts don't have ways to stick together. The shorts also don't fit easily inside the legs to be able to work (however I'm making rubber casting so it'll be flexible enough to fit)Incredible work. Inspiring me to start my own. The Don Post files you're working from say "OUTDATED" in the title. Do you know why that is? Is there an updated file somewhere? I can't seem to find any other wearable stl of the Don Post scans.
