We really enjoy playing the rollable backgammon design by  NickGHauge, but needed a case to bring it along when travelling. 
This is my version of a box for the game. I have included the Fusion design file. Please change the model as you see fit, and let me know what works /doesn't work for you. 

It is a rather tall and narrow design, so I recommend lowering your head speed when printing this.  

The model file settings works fine on a P1S Combo.
