Rack & Pinion BB Launcher

A fully print-in-place BB launcher featuring a different firing mechanism from my previous designs. Instead of using a linkage system, the trigger acts as a partial gear that drives a rack, pushing the BB directly out of the barrel. An integrated spring returns the trigger to its original position. Features: Fully print-in-place mechanism. Rack-and-pinion trigger system. Integrated spring for trigger return. Small roller at the barrel exit, designed to give the BB backspin and potentially generate lift during flight. Built-in magazine with viewing slots to check how many BBs are left. Safety: Use responsibly, wear eye protection, and never aim at people or animals.
