I created this model as a project for my pupils in school that will learn how to connect a LED circuit and how to solder before going on their xmas break.

Any large enough shade/diffuser with a 32 mm diameter hole will fit on the stand, so feel free to make your own. The LED mount has mounting holes for a 3 mm LED as well as for a suitable resistor. The stand also features a hole to let in a usb cable and a cable holder to keep the cable from tipping the whole thing since it does not weigh much.

The LED mount and the stand has a 0.1 mm tolerance so a press fit should be enough, no glue required. I printed my tree in clear PETG with a single perimeter and the rest in white PLA.
