This is a printable pcie bracket, two slot, standard height, for a PNY 1660 super. I printed using PETG. This should be fine, while gpu temps may get above the 80c limit on the PETG, the air temp coming off the cooler will likely be quite a bit cooler, so it is very unlikely to melt. If you're very concerned you can always print the bracket in ASA.
