Christmas tree with embedded addressable LEDs using color change feature of PrusaSlicer. 3D print is divided in 4 stages with in total 25 LEDs. Using a Trinket M0 Arduino compatible board and a Li-ion battery to drive the LEDs and generate nice light effects.

Print instructions

Stage 1-3 have a color change at 5mm to put the LEDs inside. Stage 4 has two color changes at 5mm and 40mm, so also the top LED can be placed before printing the clear top. The stencil is only used for stage 1-3, for stage 4, just print the first 3.5 mm of stage 4 as a stencil.
