Parametric BSPP (G) / NPT Threaded Pipe Adapter

Parametric BSPP (G) / NPT Threaded Pipe Adapter – Customizable ConnectorThis is a fully parametric pipe adapter designed for BSPP (G) and NPT threads, built for reliable 3D printing and real-world use.Unlike many “decorative” thread models, this design uses standard thread dimensions (major diameter, pitch, and thread angle) and generates true triangular thread profiles via the proven threads-scad library. The result is stronger, clearer, and more printable threads that actually fit.🔧 Supported StandardsBSPP (G / ISO 228) – 55° Whitworth thread profileNPT – 60° thread profile (nominal straight-thread form for printed parts)Common sizes included (expandable):G: 1/8, 1/4, 3/8, 1/2, 3/4, 1, 1-1/4NPT: 1/8, 1/4, 3/8, 1/2, 3/4, 1, 1-1/4⚙️ Fully ParametricYou can customize:Inlet & outlet thread standard and sizeMale or female threads on each endThreaded lengthWall thicknessTransition length and shapeOptional hex wrench flatsThread tolerance (single parameter for fit tuning)All customization
