Stars with rounded edges perfect for use with glow in the dark filament. Versions with (for hanging) and without hole (for fixing to wall with double sided tape or other adhesive).

Tested using PLA glow in the dark filament from Polymaker in this case and strung together with some clear fishing line lying around

0.4mm nozzle

0.2mm layer height

5 wall perimeters

5 top layers

5 bottom layers

Why so many solid layers? More filament = higher ability to absorb light = longer and stronger luminescence
