Roomba bumper add-on, doorstep stopper

Better printable doorstep stoppers. Let Roomba detect doorsteps that are normally too low.
This thing is customizable. Made for the 500 series. The offset of the screws might be different in other series but this is custumizable too. Please publish the remix with the working settings for your Roomba version.

The customizer does not zoom to the visible thing so it's hard to see what you set. I hope it is somewhat self explanatory.
