Gears for the rubber brush drive mechanism. If the socket for the square or hexagonal pin of the rubber brush is damaged, the roller will stop rotating and Roomba is no more capable of picking up the dirt from the floor.
Repair requires replacement of whole assembly which costs over 100EUR/100USD. This gear allows to repair it cheaply.
Print using PETG filament. It is necessary to extract the brass bearing from the original gear (heat the plastic to extract it more easily) and press the bearing into the new printed gear (preferably using a vice, press it in deeply, about 0.2 mm deeper than the surface of the gear).
After printing, the support must be removed first.
