Recessed Light Trim Ring

I used a non-standard ceiling material in my basement, thinner than normal. This mean that the trim rings that come with the can lights can not be used. 
This is a basic trim ring that I used with 8mm thick ceiling material, as opposed the 13 - 19 mm material. I used IdeaMaker slicer to apply the pattern to the sloped side. I'm sure you can do similar with PrusaSlicer as well.
