The author remixed this model.
The original model was designed for Slamtec's RPLidar A2. Fortunately, we now also have available in our labs the Slamtec's RPLidar S2!
Although both sensors share the same dimensions for bolt holes (which is all we needed), I've decided to update the top surface of the bracket to accommodate the new footprint of the RPLidar S2 sensor.
