About this 3D model

This is my first Ikea hack, make a Mulig shelving unit proRoomba! Have you ever wondered why there is furniture that is not proRoomba? Why have a Roomba if it can't go under our furniture? My purpose is to have a "proRoomba" home where my vacuum robot can go under almost everything. I recently bought an Ikea Mulig shelving unit and found out that it needed 20mm extra space in order for the Roomba to go under. So, I designed a simple leg that increases the clearance and that’s it, my Roomba goes down the shelves without any problem! Isn't it awesome?
