I made a great white light filter with a collar and solar film about 2 years ago. Never a problem until this week when the hot weather found it and distorted it. It still works, just about, but I'm not happy with the fit of the film now.

So if you make one, suggest keep it cool or make it from something other than standard pla fibre.
