Yes, I am familiar with 3d printing, I’m currently printing my halo 3 mark VI chest. I worded what I meant weirdly, What I mean more specifically is I’m trying to upload STL to the post on this forum for people to use the free halo 3 weapon STL files I have, and they show up in my folders when normally looking, but on 405th forum post when I go to upload they are not there ?
