Roborock S7 Side Brush

prusaprinters

After two years of use, I am confident that this replacement for the original side brush is durable enough. The outer and inner part is printed from PLA, the brush arm and mini brush are printed from TPU. There is no need for supports. You need to print 5 brush arms and then cut the outer part in the middle of each one. The outer part has the screw hole covered with one sacrificial layer. All parts fit tightly together. Just put everything together and screw it in.
