Glow Ring Flat (Require Glow In The Dark Filament)

thingiverse

This customisation object lets you attach a glow-in-the-dark ring around an object, making it easier to spot in the dark. The ring has a slit for straightforward mounting. We tested this with glow-in-the-dark PLA filament on a fire extinguisher with a 30mm neck and found that it's flexible enough even at default base thickness. For optimal results, print with a minimum of three wall thick shell so there's enough space for the glow filament to collect brightness. Remember to frequently swap out your nozzle tips when printing glow filament - it can be abrasive.
