Side Brush Gear for Roborock

The gear of the side brush was defective (see images). Several of the cam teeth were broken.I redesigned and rebuilt this part from scratch.The robot showed the issue that the side brush only rotated in the corners. This was most likely caused by the broken gear, possibly after the brush got stuck or pulled on a cable.For best results, printing with a 0.2 mm nozzle is recommended to achieve sufficient detail and durability.When installing, the finished model needs to be slightly pressed into the housing between the two adjacent gears (above and below). Once installed, it fits well and the side brush works normally again. The Part is fitting for the Qrevo Master. But I guess it´s fitting for some other models or even firms too. This is a compatible replacement part, not an original component from the manufacturer.
