Hi, I'm Willem, I'm from Vermont, and I'm 17.
This is my year and a half-long project, creating a 1/10 scale LMTV military truck, based on the Stewart and Stevenson m1078. I made one for myself, and more recently, one for my friend. This truck was 100% meticulously designed by me in fusion 360. It has been a great learning experience and a hell of a project. The truck is also very functional and features a durable metal drivetrain with 3d printed (double-helical) gears for the lower torque applications and off-the-shelf brass worm gears as the final 30:1 axle reduction. It also features printed telescopic driveshafts. Almost the entire rest of the truck is printed out of about 2kg of pla and TPU. The whole thing can be printed on my Ender 3, despite being about 600mm long when complete. I designed TPU tires for the truck because 130mm rubber hobby tires are expensive! (Although I recently splurged on some) I also made TPU tracks that work incredibly well, and have plans for a camper (see pictures) and some other accessories as well as a 6x6 version. Recently with the addition of a fully boxed frame, I was delighted when after an hour of intense rock crawling, not a single thing was broken or fatigued. Progress! Theoretically, the whole thing costs as much as the materials to make, which is much more sustainable for me, and I hope to continue developing the truck and its accessories as I head into my senior year. The Snapmaker is such an awesome tool, I would love to laser cut Lexan for windows and plastic sheet for lighter weight body add-ons, never mind the potential of a CNC router with that awesome rotary module.
Although I didn't customize a store bought truck, I would argue that my truck is as custom as it gets. Every part, from the drivelines, to the interior, to the frame is custom. This is such a cool idea for a contest, it brings out some real talent in 2 hobbies that I appreciate. Thanks, Chris!
