About this 3D model

My design combines two pens and a chess game, complete with the board. Use it as a pen, or unfold the two pens shell to a chess board revealing the chess pieces inside. The pen and chess board is made for printing on a 3d printer. The overall size is of the pens is 22cm high and 2cm wide each. The chess board is 16cm x 16cm and the chess pieces is in average 1,5cm in height.
