Looking for a viking axe, but not wanting to deal with glue or non-printed metal screws? Search no further :)
All elements printed with 20% infill and no supports except for the axe head which was printed top facing down with supports “Touching Buildplate Only”.
Tighten each of the three screws until the handle orientation and gap is at the desirable placement.
Note: Handle pieces can be repeated for an extra long handle. If screws break to easily increase infill above 20% (depending on needed ruggedness).
UPDATE - 12/15/2023
As an added bonus, the axe head can be unscrewed and replaced with a chain and giant spike ball to create a cool medieval morning star weapon prop.
Added an "optional_print_adjustments" folder which has a axe head with a flat top. A little less fancy, but can be printed faster and without supports. This folder also contains screws that are 98% of the size of the regular ones in case the normal fit is too tight on your prints.
The author remixed this model.

Also, added central handle objects from @WF3D's awesome Assassin's Creed model (with new screw holes applied) at: https://www.printables.com/model/109074-assassins-creed-valhalla-eivors-axe
