About this 3D model

This is a housing for the clock kit I bought from BangGood. I bought this: http://www.banggood.com/DIY-DS1302-Rotation-LED-Electronic-Clock-Kit-51-SCM-Learning-Board-p-956298.html but they have since made a slightly different version. They now sell a box to go with it but what the hey - why not make it? It turned out really nice. The only thing I didn't like is that it only came as a 24-hour clock.
