If you like Bambu Lab's mouse design but you are not happy with the range or the sensor accuracy, the best option is to use the circuit board of a different mouse, in this case, the cheap Logitech M171.

This model is inspired by user_1896508557's design for the Logitech M170. I could not make his design work, so I had to redo most of it to fit my needs. It also uses the changes made by vanbluca to round the back of the external case, and of course, this would not be possible without Bambu Lab's original model.

The wheel is too close to the left, you might want to sand that part so it doesn't drag. Maybe somebody with Blender knowledge can fix this in the geometry.

It needs the screws of the original Wireless Mouse 002 kit, and you should re-use the slider pads from the M171, or use the ones from the kit.
