The other halo pelican stl on the interwebs is broke hard.
Bad file.. won't slice, won't print.
Nevermind its a hard print even if you could fix it.
SO.. I sliced it in half. One half had all kinds of broken stuff in it.. the other half was fine. Here is one half and it's mirror.. works great!
Even in the print of the one this is remixed from you can see the messed up window. Non manifold to beat hell and won't fix easily.
