Print the parts here, and modify them in any way that you want to create your own Christmas Train decoration. I had this small motor, but a stepper motor or a variable speed motor would be an awesome upgrade. How about a touch sensitive RGB LED to change colors!The Mountain Tunnel can easily replaced with another scene, as well as the Train turntable, could be changed to sleigh and reindeer, or race cars, or whatever says Christmas to you. Either way, have fun!https://youtu.be/1saqugT40Bw
