Roomba vacuum robot square chair leg stopper

A simple stopper for square chair legs, so a robot vacuum like the iRobot Roomba does not get stuck on top of the legs. Can probably be used for other furniture.


[Version 2](https://www.thingiverse.com/thing:3325479), that is included in this thing, was done by [TheFisherOne](https://www.thingiverse.com/TheFisherOne), to make the code more friendly for the customizer, and fixed rendering issues. Thanks alot!
