Hello,
here is one of my design. It is a controller holder remiw with a lightbox at the back and front compatible with ps5 and xbox controller
For this, you will need a 1 meter led strip. Mine is a multi color but a simple yellow or whit led is fine too.
For the europeans, you can fine a led strip in the Action shop that cost 0.99 euros. THe back is large enough to hide the battery box
Some glue or some double tape is neccessary to hold the eye at the back
Just need to fold the led strip as you can in order to make it fit in the small cloud
Everything snap and fit together
