I bought some eSun PETG filament to try this past week after hearing that it was easy to use like PLA and seeing the beautiful colors it was available in and thought I would share a sample print.

This print ended abruptly as I apparently turned the stepper driver too low on the Z axis, so please excuse the top.

This was printed at 250C/100C at 0.2mm layer height. It is difficult to capture the "sparklies" in the coloring, but this should give you some idea.
