I didn't like the simple design with the two acrylic plates, so I constructed something according to my design preferences. I aimed to keep it as simple as possible, which is why there is no attachment option for the board and the sensor.
I designed it so that both can be centered in the housing and then easily fixed with 3-4 points using a hot glue gun. To achieve a smooth transition of the curves, it was oriented with the visible side facing up during printing, and the support settings in the Bambu Slicer were set to 'seamless.'
Perhaps someone else might find it useful as well... Enjoy!
