Fully 3D Printed Train Air Launcher

This model is printed very quickly, you only have to insert the knobs with the wheel into the wagon and it is ready to play. It is also fully compatible with Brio, or Ikea Lillabo. Press the button as hard as you can, it is very stable and you don't have to worry about it breaking.
You can also use it to play a race to see who gets further.

Important. For the knobs it is recommended to use a stable filament and to insert them carefully and straight into the wagon, as they sometimes break when inserted, I recommend printing a few more to be on the safe side.
