It gave a warning about a floating object, but it printed perfectly. I used Bambu Black and Bambu Glow Blue. My phone camera made the glow a hell of a lot brighter than the glow, but it's great! Thanks for the work!
Looks good :)
The Floating object warning is for the text, to get the white (or glow in the dark in your case) to print in one flat layer I split and seperate as individual parts. It's how I did multo colour before an AMS was an option on idex printers.
I have added two profiles for you to try.
One is 1mm thick, has no solid back. The other is 2mm, has a black back, I'd go with the second one personally.
