Zeropone Air Duster Smaller Nozzle

I recently picked up a USB rechargeable air duster to clean out electronics. The included nozzle is high flow but also pretty wide. I wanted a smaller more narrow nozzle for directed airflow. 

This has a 20mm outer diameter for connecting with the duster main body and a 7mm inner diameter opening for the air outlet. Walls are 2mm thick. It ends up printing with 100% infill since it's basically just walls.
