Here is my Electroluminescent wire sward from Alita film. Print it in clear PLA and put blue EL wire inside. Paint outside with silver paint except the traces on on sward. In order to fit electronics inside you have to take it out from original box (see pictures). There is a slot for standard size mini micro switch which activates EL wire whenever you like.
I'm really happy with the result, but if you have any suggestions please message me :)
Update 12/02/2019 I have made small changes to the design and now the EL wire will fit right to the end of the sward.
Also on the picture I joined blade with gripper other way round, that has been fixed too.
Update 14/02/2019 This is final version now. Previous version wasn't split evenly. In this version left and right are mirrored.
I'm a geeky physicist and I'm obsessed with 3D printing and 3D design :D
