Glueing A 3D Print to Metal?

[Eric1001]

I have motor that I need to glue an 3D printed (PETG) encoder disk to its shaft. There is very little (if any) force on the disk.
The motor gets hot during operation. My thinking I should use a heat curling glue.
My question is what glue to use.?

If it gets hot, think epoxy not hot glue, otherwise your encoder becomes a very slow rotating surprise.

Hot glue won’t survive motor heat,so yeah go epoxy, prep surfaces properly and let it cure fully before spinning it up
