A replacement brush suitable for the Roborock S7 Max Ultra and similar models.

Use TPU for durable printing. Here, I've been using this model extensively for three months. No warranty provided!

The model I designed myself is absolutely perfect. You need to remove the internal components from the old brush, including the rod, foam pad, and spacer. Then, just install all the components into this 3D model.

Wish you success and enjoy printing
