Lighted Christmas Tree
Description
### What is this thing? It is a Christmas tree that you can put LED lights in. I was looking for something to print as a decoration and could not find anything I liked. I did find a Christmas tree that I liked but it very small. I recreated it much larger and designed it so that you can put small LED light strips inside. ### The design The design has cutouts at the top and bottom of each level. The center pole has a cutout to run wires for the LEDs from one level to the next. In the base there is a cutout that can hold a NodeMCU. ### LEDs and Control For this I would recommend using the higher density 60 LEDs per meter. You will get just over 20 LEDs in the tree with that density. I also recommend using 5V LEDs. The NodeMCU can handle 5V if you use the Ext pin because it is before the voltage regulator. So one 5V power supply with no need to drop 12V for the LEDs to 5V for the NodeMCU. ### Printing I printed mine with no support. The bottom section where the node MCU goes can get a little stringy without support but it is on the bottom where no one will see it. One note on Filament, the LEDS are in the center of the tree so it is best to use some transparent filament. I print 3 different transparent colors and they all worked well. ### Assembling Assembling the trees takes a little patience. They themselves are fine but soldering the placing the LEDs in small places can be challenging. To hold the trees together I used hot glue. So far that seems to work very well.
