Merry Christmas 2019 "Gift to All"

myminifactory

I created this in Blender 2.80 as a gift for everyone in 2019, building upon the previous year's design (https://www.myminifactory.com/object/3d-print-merry-christmas-gift-to-all-79386), including the solar version (https://www.myminifactory.com/object/3d-print-merry-christmas-solar-version-gift-to-all-79488). I listened to feedback and started with a circle in Blender, crafting this design from scratch using a moving train. It's optimized for as many printers as possible, featuring a 200mmx200mm base. Every part and tree is carefully designed without requiring support, making it easy even for beginners. This version is complete and tested, with hollow tubes in various locations to accommodate electronics inside or outside the print. You can add lights to buildings or the Christmas tree. Update: November 6, 2019 Gear04 is slightly smaller, suitable for less accurate printers. Schematics for the motor setup are available at https://easyeda.com/shermluge/microwave-motion-and-on-off-circuit. Even with adding LED's and 1k-2k resistors, I only draw 40ma through the Mosfet when the motor is on.

Put a jumper on the microwave motion to change from 2 seconds to 30 seconds. Use a 22nf capacitor for 10 seconds. To adjust distance, add a 680k ohm resistor on R-GN to change the range from 7 meters to about 3 meters. Assembly video: https://www.youtube.com/watch?v=XLeWQsXkJHY Merry Christmas and enjoy!
