Mario Super Star LED Necklace

All parts are designed to be printed in the orientation they load into the slicer. This means the star front and back do print vertically and I strongly suggest a good brim to keep them in place. The built in supports should just snap off but that will vary based on your printer tolerance.

The shell is 0.8mm thick so designed for two 0.4mm walls. I printed mine with a subtle fuzzy skin as I felt that would help with light diffusion better.

I used six 5mm diameter white LEDs and powered them with two CR2032 batteries using this holder. They are wired up in three parallel sets of two LEDs in series with a 330ohm resistor on each set. These are the LEDs and resistors I used but really any should work.

The eyes are super glued to the front shell (drafted side faces the star). The battery holder is super glued to the rear shell. The LED holder has the LEDs hot glued into it and that is then super glued to the inside of the rear shell. I suggest if you want even lighting to glow some hot glue on the front of the LEDs to function to diffuse the light. Using frosted LEDs or even a thin layer of parchment paper also work fine. Once everything is working the two shells are super glued together and you are good to go. 

The shell should ideally be printed in a yellow filament that will allow light to pass through. LED holder can yellow/white/transparent and it shouldn't really matter. Eyes are obviously meant to be black. I used Printed Solid Jessie Yellow Bird, Black, and Quarter White PLAs for mine.

All parts were printed on my Voron 2.4.
