3D Print a Drill-Powered Helicopter Toy Because It’s Simply Fun

Back in the day, kids had to settle for simple toys like spinning discs that flew into the air. Nowadays, you can get a fully remote-controlled helicopter for around $30. [JBV Creative] brings back the charm of those simpler toys with a modern twist, using a 3D printer to create a fun spinning disc toy.

The design is straightforward. It uses a power drill to spin up a geartrain, which drives a small disc propeller. Once the propeller spins fast enough, it launches high into the air. The geartrain attaches to the drill via the chuck and connects to the propeller with a simple toothed coupler. There’s also a hand-cranked version for those without a power drill.

Launching the disc is easy. The drill spins the propeller up to speed. When the drill’s trigger is released, the drill slows down, and the propeller spins free of the toothed coupler, generating lift and flying into the sky.

Files for this design are available online for those interested in building their own. This toy could serve as a great basis for a design competition, where students could optimize the gear ratios or improve the airfoils for better performance. Similar designs have been seen before, and a video demonstration is available.
