The original lenses are very delicate so if one was to drop the knobs into the sink while cleaning the range top, the original plastic lease break and the cool blue effect of the LED around the knob doesn't work as well. The replacement lenses are identical in size and shape as the original and are best printed using clear PETG. The extra heat tolerance of the PETG turns out to not be needed as the knobs are far enough away from the heat that they do not get hot, but better safe…. There original prints I did in blue and that turns out to be too dark. Clear or Natural is better.
The author marked this model as their own original creation.
