I think I quiet enjoy making replicas of historic weaponry. Not exactly a complicated design, I think this mace turned out quite well. 
All parts straight out of the printer, maybe I’ll make another one some day that I’ll paint and weather, for that extra bit of realism.
Nice Job. Would have not wanted to encountered one of those. 3D printed version could do enough damage to put one in AE for a 7 hour waiting - goodness know what it did to the poor beings back in during medieval times!
Indeed, it’s a heinous weapon. These flanged ones were made to dent or even pierce armour.
