Goof Ring

This goof ring was for a 6inch light. To modify this for your use case you need to measure two things, the first is how big of a hole you are trying to cover, the second measurement is for the size of your light, adjust the inside circle(the negative shape) to be slightly smaller(in my case about 1/10 of an inch) and the outside circle to be bigger than your hole(I did mine about ¼ of an inch bigger). Mine was done with 15% infill but if you need it to be more study just bump up the infill, I used this with LED lights since I knew it wouldn't produce heat, using it with other styles of light is likely a bad idea.
