3D model description

  • Complete project folder with .STL files, parts list, wiring diagram, build instructions and Arduino code

  • Project electronic cost estimate: €85 or $95

Designed and printed this powerful and automatic tennis ball launcher for our overly active German Shepherd. Because he has enough space to run around here it could be quite a bit of a powerful ball launcher. And that's what it has become! The GIF in the Pictures shows the first test. (Without housing still) That was about 10-12 meters but after a few minor adjustments it now shoots consistently about 30-35 meters. Parts list with internet links, electrical diagrams and Arduino code are all in the folder. If you still run into problems during the build, you can always contact me via my e-mail. I added my email address in the top line of the Arduino code.

  • Housing:

I made the housing from 5mm white foam board in combination with white duct tape. Cheap, easy to work with, light, strong and also a neat finish! The .STEP file of the housing is also in the folder if you need my dimensions.

3D printing settings

I recommend printing all parts with a 0.8mm nozzle, at least 3 walls, 3 top layers, 3 bottom layers and 20% cubic infill. If you want to print with a 0.4mm nozzle, stick to 6 walls, 5 bottom layers, 6 top layers and 30% cubic infill.
