Gridfinity Double Tempo (tissues) box

A 3x3 (126 x 126mm) Gridfinity box that holds 2 tempo tissues packs next to each other. (108 x 108mm inner space).

Thanks to @jdegs who provided the Filled-in Gridfinity Boxes (For Customization) that I used as a base for this model. 

Added cutout for 2 tempo (tissue) packs
