3-n-1 Upgrade Cubes

Not enough room for standard upgrade module or for other modded upgrade modules? Well the cube is the answer.

It is 1x1x1 6 sided upgrade module, based on meows famous double-sided modules. (same boost numbers used in mod.)

Also since this a 3-n-1 mod it does Productivity, Effectiveness, Power Efficiency in a single cube. No more mixing upgrade modules.

Enjoy the mod.
