modular wall/spacer system with 3" window vent

this model uses very tight friction fit walls and joints to create a strong modular system. you can combine longer or shorter walls and joints in order to stack vertically or horizontally. lengths is 5" by 2,4 or 6" tall. fully scalable in bambu studio and can be used with any combination of walls or infill depending on application. i created this to exhaust my p2s to a window using 3" duct and the FNATR glass riser system.
