Update 3/7/17:
Thanks to Dayne427 's awesome Redhood variant print (go check it out!) I've edited the back portion to include room for ears so that the helmet is easier to wear. I'm not sure what orientation Dayne427 printed the back portion but I included a pic of the Cura settings and orientation that I think would work best.

Note 3/5/17:
I kinda just realized that I really didn't explain how the mask and the back were supposed to attach. There are two vertical posts in the interior of the the back part. Those were originally meant as posts that one end of an elastic band could wrap around. The band is then supposed to feed out of the slots on the back of the helmet. The other end I originally planed to have Velcro that stuck to the mask. The interior of the mask on each side near the ear there should be a rectangular recess for the Velcro strip. This way the helmet should be able to slip onto the head pretty easily (theoretically).

Make sure to check out awesome makes by JimmyTime and Danye427!

Update 1/20/17:
Hey! V4 is here. So some tune up (strap anchor has some fillets now, the forehead area's thickness is definitely better [not crazy thick]!) I've also sliced it a new way that I think should make things easier. Removed the old files cuz things were getting confusing and cluttered but if you want those for whatever reason just message me!

Update 1/16/17:
Full Crossbones head gear! Mask + Back Cap (minus strap). Broke down pieces to fit my plate but message me if you'd like me to split some other way. Upload half, figure you can mirror on your own (right?) Still trying to find time to print, but please share if you beat me to the punch!

Update 1/14/17:
-Hey ya'll. V2 > V1. Touched up the temple area. Most important got rid of most of the super thin and sharp areas. Tossed in some fillets...more to come!

1/12/17:
-Crossbones Mask as seen in Captain America: Civil War.
-Seen some others on-line that were kinda eh so I thought I'd give it a go. I used screenshots from the Kabam app game Marvel Contest of Champions.
-Personally haven't split and printed yet (if anyone beats me to it Good Luck!)
-2nd half (back part) should be coming soon!
