I designed this in Blender 2.80 as a gift for all for 2019 (last years was https://www.myminifactory.com/object/3d-print-merry-christmas-gift-to-all-79386 , solar version https://www.myminifactory.com/object/3d-print-merry-christmas-solar-version-gift-to-all-79488 ). I listened to what people suggested and started with a circle in Blender and created this from the ground up with a moving train. It is designed for as many printers as I could, its a 200mmx200mm base. I created it looking at every part and tree, not needing any support. I wanted to make this as simple as possible even for beginners. It is one very easy print.
This version works and is complete and tested. I put in hollow tubes in many locations so you can put electronics how ever you prefer, inside, outside. Lights in buildings or Christmas tree.
Gear04 is a tad smaller for printers that are less accurate.
Schematics for just motor set up:
Even with adding LED's with 1k - 2k resisters makes it so with motor on I only pull 40ma through the Mosfet.
Parts and were to get them (very low cost)
100nf capacitor for motion sensor if used.. Put on C-TM - jumper on microwave motion to change from 2 seconds to 30 seconds. For 10 seconds use a 22nf capacitor.
To adjust distance, you can put a 680k ohm resistor on R-GN to change the range from 7 meters to about 3 meters.
Merry Christmas and enjoy
