I was surprised that this worked and that it was actually useful.
This print was a trigger for my parents' kettle, where the original broke apart. The print came out pretty accurate, considering I followed a photo of the parts with polylines in Fusion360. The problem was that the PETG and PLA+CF prints would go soft and deform. It isn't boiling hot since you pull it with your finger, but apparently over 60C.
I had a pyrex dish that my wife donated and some sand on hand, so while she was out I put a new PLA+CF print in the oven at 175F for an hour. The oven had been preheated for 1/2 hour before but still wasn't up to 160F on a separate oven thermometer. When it finished, it was at 175F. I let it cool on the stovetop for about an hour; I could see no significant deformation. Since fitting it on the kettle, it has been used several times with no softening or warping. Below is a pic of a new print and a used/warped print.
This is the only thing I've tried annealing, but it was pretty interesting. Maybe not a huge change in heat tolerance, but enough.
