You'll require one print and a Pneumatic 12mm-1/4" BSPT male fitting to proceed. I had printed with two shells in advance just in case of any complications. Upon completing your print, while it's still warm, you should heat up a single 12mm-1/4" BSPT sized fitting until it's extremely hot. As the fitting reaches an ideal temperature, it will seamlessly attach to the print without encountering any issues. During my first attempt, the fit was slightly too tight, so I promptly heated the entire part with a preheated 12mm-1/4" BSPT male fitting before proceeding with assembly. To seal the device as desired, utilize casket sealing techniques combined with strategic cable tie placement to achieve a perfect secure fit. The upper section of this item is designed to accommodate a set screw.
