Ah, we were wondering where that came from. Glow-in-the-dark filaments are pretty abrasive, so they damage brass nozzles. You need a hardened nozzle to print it without wear issues. I hid the spool in our super secret hiding spot for things that shouldn’t be used. I do have a 0.4mm hardened steel nozzle that I could install on one of the printers if you want to use the glow filament. We will have to put big obnoxious labels on it to warn people not to use it with brass nozzles.
