Second Annual AMUGderby
Last year’s AMUGderby was an overwhelming success, so we are bringing it back for AMUG 2025. Ignite your creativity and “start your engines” (figuratively) by letting gravity do its thing in the AMUGderby.
Whether it takes you back to your childhood or it’s the first time you have created a derby car, please join us for this fun event. We’d love for you to compete, but spectators are encouraged to join in the fun.
The AMUGderby will take place on Wednesday evening (April 3, 2025). Gravity-powered racecars, built by AMUG Members, won’t have wood bodies made of pine. Instead, competitors will design and print the racecars using AM technologies and materials.
New for 2025: 2 race classes
The 2 race classes for the 2025 AMUGderby are Standard and Open. Both have specifications for the derby cars.
The Standard Class pairs official BSA® axles & wheels (buy them here) with 3D-printed bodies weighing less than 6 ounces.
The Open Class allows for heavier cars (10 ounces), mechanical propulsion and custom wheel & axle configurations.
Two ways to win
The cars will compete head-to-head, and the fastest car in each class will be named the champions of the 2025 AMUGderby.
AMUG will also award a ‘Best Design’ prize. So, while iterating your design for raw speed, let your creativity run wild.
Guidelines
The derby won’t be a free-for-all in terms of vehicle specifications. There are limits to size, weight, and configurations that will be confirmed during pre-race inspection.

Registration
Racer’s registration is not mandatory, but it is strongly encouraged.
