transcone / cone / triangle warning board


The cone and warning triangle board are often use in road construction.
but the storage problem is still inconvenient, we combine the cone and warning triangle board to one new cone.
The concept is make the cone is also warning triangle board, use the folded structure to storage it and change it.
