Stackable Toilet Paper Dispenser

I believe I solved the assembly without adhesive issue. I basically inverted the tabs along the edges, added 3mm to the boarders and added 3mm feet to the bottom (ever have a leak under the sink? you really see how absorbent toilet paper really is!).
I also increase the general dimensions to accommodate larger rolls. I am missing the optional bottom side with cutout (forgot to export it) but will post at a later time.
