rainbird 1/2 in shrub adapter, PA-8S replacement

This is a replacement for the Rainbird PA-8S adapters for shrub spray nozzles. The top male thread is a proprietary, 5/8 in, 28 TPI (Threads Per Inch) unified fine style thread. The 1/2 in female NPT thread has some steep overhangs so a thin layer height is absolutely necessary to avoid detached perimeter lines. For a successful, functional part print slowly in PETG or ABS/ASA with a 0.1 mm layer height.
