About this 3D model
This is an Snowman with RGB-flashing LEDs. The height is about 120mm There is the snowman itself and a ground plate for LED and a CR2032 coin cell. With on/off rotary switch. You need a cr2032 coin cell and a LED. I prefer a RGB-slow flashing LED you can find on Ebay. I used two LEDs for better shining. Here is a video on youtube https://youtu.be/WlUVYs7S-2o Have fun!
