Hi,
This looks really cool. I am trying to design my own elevator with my kids. I have a couple of questions:
1. What type of motor are you using to open the doors? It is attached to the top of the elevator, right?
2. Could you explain the mechanism you use for the double doors? I can see that the outer doors have pegs. I guess the inner doors push those pegs to open and close the exterior doors. I can imagine the mechanism to open them, but I can't imagine how you get them to close.
Thank you!
