The tree cake includes a keychain with a prepainted 3MF, and a hollow version! To light up the hollow one I used one of those small boxed twinkling led lights, but a tealight will fit great as well! I also used translucent filament.

I printed the hollow with 2 walls and Archimedean chords in bambu slicer, lightening infill would likely work well as well! depending on how translucent your filament is you can also use 3 walls. + + 📌This model is for PERSONAL USE ONLY, to sell prints of these designs you will need to SUBSCRIBE TO THE MERCHANT PLAN available on my profile page - Click here📌
