Christmas 2019 "Gift to all"

cults3d

I came up with this year's "Gift to all" after releasing last year's Merry Christmas gift and listening to what people requested. I really worked hard on designing it to be printed in 4 pieces without supports, making it easy to assemble. It uses few electronic components and is designed to have all electronics on board or away from the model. I made it with many wire tubes so you can run light to windows, motor, motion sensor, or whatever you want to add. The Christmas Diorama with moving model train comes with a diagram for a motion on/off switch. Here are some parts you'll need: * Motor: You can find one on eBay at https://www.ebay.com/itm/New-Micro-Gear-Box-Speed-Reduction-Motor-Electric-Geared-Motor-6V-50-to-300RPM/123598737052?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 * Motion sensor: You can find one on Amazon at https://www.amazon.com/Maxmoral-RCWL-0516-Microwave-Induction-Intelligent/dp/B07S221PB4/ref=sr_1_6?keywords=rcwl0516+microwave+radar+sensor&qid=1563916285&s=gateway&sr=8-6 * Electronic switch: You'll need a 2N7000 mosfet, 10k resistor, and 220 resistor. Even though it's a 6v motor, I just run it at 5v and with the rpm as 100rpm it works out just right.

Thank you to 3D Printing Professor for your help. Update 7/30/19 - I fixed a problem with electronic box cutout and replaced christmas-train4-mtn-01 with christmas-train4-mtn-04. Update 11-6-19: I've uploaded Gear04 for printers not quite as accurate.
