Iconical warglaves from the Warcraft -saga wielded by doom guard commander Azzinoth and afterwards by Illidan Stormrage during his reign in Outlands.
I needed to try the LED glow effect on sword -type weapon along with the warhammer I made, and it turned out pretty well in my opinion. The problems with sword weapons are largely the limits of the construct stage size; to accompany LED's the blade had to be thicker than the LED's itself, and the thicker the blade the bigger it had to be in all the other measurements also to keep realistic look instead of becoming "blocky". This might make an issue due the size of the blades which may end up being hard if you've issues with warping to print.
Manage bit printed from PETG blades, from PLA. Painted using Citadel miniature paints and four LED's inside the handle pointing at the points of the blades the create the green glow.
