Heart Glow in the Dark
For Valentines Day, here is one littlebit different heart. Its made from glow in the dark filament and is quite nice if put over mirror. "Charge" it with LED torch, UV led is faster if you have any. For more dramatic effect, print perimeter with black filament.
Filament: Glow in the Dark PLA (or another, green is usually most brightest color)
Printer Qidi Plus 4
Support: no
Skirt: yes for outer perimeter (maybe not needed but its quite thin and contact area is minimal)
This is snug fit. If your printer is not precise, made outer part littlebit bigger (maybe 0,5% to 1%) and use superglue if it become too loose. This is in two part, if you want experiment with color combinations...
