Description
Tower Defense is a motorized disc-launching turret built on a rotating base. Using the CyberBrick parts kit and app, you can spin the flywheel launcher to speed, rotate the turret left and right, and fire discs at 3D-printed fortress blocks — your own desktop tower-defense game!
Big shout out to my Co-Creator GrantUSA (@GrantUSA_3426896). Together we designed and tested this model through many iterations.
How it works:
A 360° continuous rotation servo drives a toothed platform gear to rotate the entire launcher tower left and right.
Two Micro DC motors spin a pair of flywheels to accelerate discs.
A 180° positional servo acts as the disc-pusher trigger — when activated, it pushes a disc between the spinning flywheels and launches it.
Please review the attached manual for printing and assembly instructions. Standard print settings should suffice with supports as noted.

WARNING:
This device launches small discs at speed. NEVER point the launcher at people, animals, or fragile objects.
Keep the launcher pointed in a safe, clear direction at all times.
