Created mainly for the 3 cup filter you fold yourself. I have found it very handy indeed.
Note that not all Chemex brewers are created the same. I have 2 8 cup brewers and my guide fits perfectly on one, but is loose on the 2nd... So your results may vary. It will get the job done even if it's a little loose.
Thrown up here in case others may find it handy.
I use PETG as it is food safe. No supports needed.
