Clothes horse stopper for robot vacuum (iRobot / Roomba) - Customizable

This barrier thing prevents a vaccum robot like Roomba iRobot to climb on the feet of a clothes horse, and to stuck up in place while damaging its brushes.

Scale it and cut it to the desired length in your slicer software before printing, or customize using Freecad.

Full width is not needed. Those I use are 15cm and 20cm width and it's working fine.
