Glow Ring Cylinder (Require Glow In The Dark Filament)

thingiverse

This is a customisation object that lets you encase an item in a glowing ring, so you can spot it in the dark. A gap in the ring makes it simple to attach. This was tested with glow-in-the-dark PLA filament on a 53mm diameter drink bottle. To get the best results, print with at least 3 layers of solid shell to give enough space for the glow-in-the-dark filament to collect and shine brightly. Remember to swap your nozzle tips often when printing with glow-in-the-dark filament - it's very abrasive.
