3-4in_NPT_Check_Valve-Print-in-Place.stl

Attempt at making a print-in-place 3/4" male/male NPT check valve. Valve uses a slim/in-line profile that restricts water flow. This design choice was made to allow the part to fit in tight spaces.

3d printed version not intended for use with potable water.

Recommended to print at 100% infill, you can use as low as 80% but it will make a more brittle part.

Requires this OpenSCAD library: https://github.com/Nicolas45Dev/NPT_Library

Supports holding the "plunger rod" at the bottom of the model must be cut after use. Unsure how required these are, plan on trying different support methods in the future.
