Monsterpocalypse Paper Apartment Insert

Just a simple box that fits within the paper apartment buildings for Monsterpocalypse. Currently the sizing of the box is .2mm shorter then each of the dimensions and it fits perfectly for my paper buildings (Not sure if there are variations in die cuts in boxed sets). I printed mine with a .3 layer height and a 20% infill for faster printing. Hope you enjoy as it makes the building a lot more stable.
