Informacje o modelu

Open spiral with exposed top Designed for attaching the LED strip to the inner or outer wall. Use any filament you like.
Closed hollow spiral Ideal for translucent filament – the LED strip slides inside the spiral for a soft glowing effect.

Recommended LED strip: FOB COB Led Light RA90, length 700 mm, width 8 mm
Controller: RF14 LED Light Strip Controller
LED strip can be glued to the spiral or inserted into the cavity (closed version)
All electronics fit inside the snap-fit base
For other electronics, you can customize the base opening using your slicer

Base prints in two parts – use supports where the spiral connects
Star needs strong adhesion – use extra brim or supports to prevent detachment
Spiral is the trickiest part – I printed it lying flat with supports, but feel free to experiment!
When printing the spiral, the supports may break off. Clean the plate thoroughly so that the supports hold well.
Slow down the print speed for better results
For the closed version, make sure supports don’t generate inside the cavity

🎁 A festive, functional decoration or gift. If you find a better printing method, share it with the community!

Version 2 broke off during printing, so I don't have the whole model. And I didn't want to print it again (I don't have another LED strip anyway 😁).

Models tested on Bambu Lab H2D and Creality Hi.

⚠ The spiral tilts forward under its own weight. I hadn't noticed that before. It can be supported with a 35 mm strut (not included in the print).
