Iconical warglaves from the Warcraft -saga wielded first by doom guard commander Azzinoth and later by Illidan Stormrage during his reign in Outlands.
I wanted to try out the LED glow effect on blade -type weapon in addition to the warhammer I made, and it turned out pretty well in my opinion. The difficulties with blade weapons are mostly the limits of the build platform size; to accompany LED's the blade had to be thicker than the LED's itself, and the thicker the blade the larger it had to be in all the other dimensions as well to keep realistic look instead of becoming "blocky". This also might make an issue due the size of the blades itself which may prove to be difficult to print if you have problems with warping.
Handle piece printed from PLA, blades from PETG. Painted using Citadel miniature paints and four LED's inside the handle pointing at the tips of the blades the create the green glow.
