Description This small 3D-printed part turns a standard compressed air quick coupler into a fun “air rocket”. Insert it into the coupler and a short burst of compressed air will launch it forward. Designed for typical industrial quick-connect fittings, the model prints easily and works well with common materials like PLA, PETG or ABS. The shape is optimized for a snug fit and smooth airflow, while keeping the print simple and fast. Perfect as a fun workshop gadget, demonstration piece, or conversation starter.
