Sprinkler Adapter 1/2" riser to 1/4" barb

Home Depot proposed a slew of adapters to go from 1/2" male to 1/4" male. This made more sense to me.

I needed misting head for shrubs and found Fogger Mister on Barb at Home Depot. The only solution they have to use this on a ½" threaded PVC is to use an adapter to a hose to the head. This is a direct adapter.

Specifically, the pipe end is a ½" NPT female thread, and the head end is female thread that matches the tiny threads on the sprinkler head.

OpenSCAD code is included, but you'll need this thread library:

I printed it on its side to put the layers perpendicular to the threads. That may have resulted in the amount of leaking I see through the threads…
