Nozzle and nut

This is my first attempt and a 3d print. This size/design was made to repair air bladders inside my massage chair where the nozzles disintegrated due to age. I'll update results after I print and install.

Nozzle size is designed for a 8mm or 5/16" rubber hose. Overall height is 18mm or 11/16". Threaded portion is 10mm or just over 3/8".
