Hi, this is the first time I make a design to be used as a cosplay so I apologize in advance (also apologies for my bad english)
I know its a little bit bigger than the original and its not well proportioned but as i said its my 1st time so....
This design is made to be mounted in 2 parts. The first one are the 3 rings with the leds inside and 6 magnets in the back of the inferior ring. The second one is the harness and it goes under the shirt like a bra with another 6 magnets and some elastic rubber (fabric, not material).
WARNING: YOU WILL NEED TO MAKE A HOLE ON A T-SHIRT IF YOU WANT TO AVOID SEEING THE CABLES ALL ARROUND.
Also, the inferior ring need a hole to pass the cables but i didnt put it in the design because i have thought that not all the people who download this desing could fit the leds or the cables to one especific hole so i didnt put it. Do it yourself later based on your needs.
For the union i used those magnets: https://www.amazon.es/gp/product/B073H43GK2/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1
For the leds i used an old piece left of another project (incoming) but here it is. Its USB powered:
Middle ring on transparent pla.
The superior ring is painted on silver/metal so as you wish.
Inferior and harness on black.
