Male adapter for Moen's weird proprietary 5/8-16 UN 2B kitchen sink threads to a 5/8 garden hose female. Probably print in PETG but my PoC is working with PLA and I'll re-print with PETG once that breaks.
The author remixed this model.
Simply cut the two models then re-assembled the appropriate ends I needed to get the adapter how I'd like.
