Bumper for the Neato Botvac D7 robot vacuum
It might also fit on other models, but that is not tested.
This bumper lowers the ground clearance to 11 mm, to avoid the robot getting stuck on chairs with U-shaped legs.
Fix this with glue or dual sided tape. For usage with thick tape, scaling is recommended.
There are 2,5 mm holes in both parts for aligning them with small pins.
