I've made this full size War Axe using Sketchup, used some pictures of real war axes and made my own version. Hope you like it.

The whole War Axe fits on one Replicator 2 printbed.

I've separated the War Axe into smaller pieces with interlocking parts for easy printing.

Update*
I've noticed that these parts are in a weird angle, so if you are going to print them you have to flip them around manually to get them straight on the printbed.

Glue all the parts together with strong epoxy and finish with some sand paper and a paint job of your choice. Good luck!
