This axe head should be compatible with the wood handles you can buy at the hardware store.  The axe handle has tight tolerances to give a solid friction fit.  There are two versions of the handle the oval one and a more printable hex version.  There are two axe heads one that is meant to be printed standing and one that is meant to lay down. This is very unsafe and dumb print and use at your own risk. Safety glasses are a must.
