Bumper Extension for Roomba

thingiverse

These are bumpers designed for Roomba extension. My Roomba 772e kept getting stuck under radiators in my flat, so I created these bumpers myself. I simply glued them onto the Roomba, but you can also drill holes into the bumper of the Roomba and use screws instead. If you need to adjust their height, just scale up or down in the Z direction - the original STL file is 15mm high, but mine came out nearly 20mm high after scaling by 1.25.
