Dual head 3D printer push button

This object is not a real remix but I made it because I saw this: http://www.thingiverse.com/thing:994005

It was a good idea but worked only with single-head Tobeca. Mine has 2 heads and it is not possible to use it.

So I built one that can work with dual-head Tobeca.

It's only the first version and it can be improved in the future.

Because of the long push zone, it is not possible to let it installed on the head. It use it as a tool.
