These are the parts I designed when making my Himiko Toga cosplay, I saw a lot of people selling their files but I couldn't be bothered. There's a bunch of pictures of the cosplay itself, I am a guy if you couldn't tell (also sorry for the low quality, thingiverse only let me upload smaller photos). A bit of warning though, there are some parts you'll need to make yourself, since some things I couldn't 3d print. For those parts I took heavy inspiration from this YouTube video:
Also, these parts don't snap together like Lego pieces most of them were superglued or hot glued together. If you do end up using these files, please post a make on here I'd love to see your creations.
