Parametric Double Thread BSPP (G) Adapter for 3D Printing

This double-thread adapter connects two external threads and is ideal for:

• Extension
• Transition
• Adjustment of various BSPP threads

Both sides of the adapter can be configured independently, allowing for the combination of different thread sizes. The integrated hexagon ensures secure installation and removal with a tool. The threads are calculated to whole turns, ensuring a clean connection and stable representation in CAD models.

The adapter is fully hollow; it can be used for the passage of liquids, air, or cables. By setting the diameter to 0, it automatically adjusts to maintain sufficient wall thickness. Thanks to its rotationally symmetric geometry, the model prints easily without support. Recommended materials for robust threads include PETG, ABS, or PA.

Typical applications:

• Hydraulic and pneumatic adapters
• Thread extensions
• Joining components with external threads
• Fixture building & DIY constructions
• Functional prototyping in 3D printing

This model is parametric; create your custom solution for inch threads.
