A fidget toy I designed based off the gas turbine engine. They can be printed in any colour you want, just choose in the slicer! Spin the front, rear or blades and the other parts will spin the opposite way.

Assembly is very straightforward, and gives you the chance to see how a planetary gearset functions. The rear cowling detaches very easily, meaning you can customise and hot swap the components to whatever colour you want.

The design is ALMOST supportless. Only the fan blades need support. I put these on a separate plate as I wanted to ensure there was even cooling across all layers, however feel free to put it on the main plate.

Important Information

• No glue should be needed, everything has a tolerance for a push fit, however depending on the filament you use, the fit may be too tight or too loose. In this case, either glue them or reprint in a different colour.
• These have been stress tested with some colleagues at my company. They haven't broken yet!
