The label on my [Pentair 262506](https://www.amazon.com/gp/product/B001F6UNKK) pool pump filter was coming off. Before I was unable to see what was what, I carefully scanned what was left of the label, imported it into SketchUp and recreated the label as a 3d print. The ring is 2mm thick and the text is 0.4mm thick. At a 0.2mm layer height, print the ring in one color and then swap filament to a contrasting color at layer 9 (assuming your gcode counts layers starting at 0). Glue it on with contact cement and bam!
