This is an attempt to create a working button, inspired from the game Portal. You can watch a video showcasing it over here : https://www.youtube.com/watch?v=B53lY6qrJAQ The cube is also 3D Printed, it has been designed by Ellindsey and you can find it here on Thingiverse : https://www.thingiverse.com/thing:173570

This design is far from being perfect, the main issue being that it needs specific parts and it won't adapt well to other parts I think. Also, the weight of the cube is unfortunately not enough to push the button.

If you still want to try this, follow the steps bellow, I'll try to be as precise as it can be ! :)
