Rollup Dice Box - Tower Short

I really like the option of having the dice tower built into the core, but I wanted the small version of the bins. So I made it myself. Still functions with the other parts from @chuyskywalker This is the version that doesn't line up with the tray from 3D Printy. If enough people want it I can make that version too. V2-Realized the little nub to help guide putting the top on was incorrect, fixed that.
