This was apparently made from Pepakura files, the uploader says anyone who wants to improve on the model is free to do so. Predator Back Pack found on #Thingiverse Predator Back Pack by Jace1969
Nice find, I've converted this to a solid model if anyone want's it. Also when opening it in SolidWorks the scale was off a bit, I re-scaled it to what I believe is correct. Also I tried to fix the sharp edges but it proved to be difficult base on how it was originally modeled/scanned. It can be done but would take some time. Since I cannot load a .STEP extension onto this website PM me if you would like it.
