A printable model of the hairclips worn by Brigitte from Overwatch the model has an empty space and a thin translucent surface so you can add LED's for the glowing parts it was designed to be printed with 0.6mm nozzle diameter but can also be printed with prettymuch anything smaller to make assembly easier you can print it in two parts by cutting it in half in the slicer and add the LED's before glueing htem together although there is a hole in the back for access once assembled
