Before printing an adapter, print the CAP first and check that it runs onto your spa. It is the only part here that has been fitted to a real tub, every other part carries the identical thread, and it is the cheapest way to find out that your port is not mine.
The port, as measured - verify yours before printing
feature | value |
|---|---|
major diameter, across crests | 59.42 mm |
pitch | 2.5040 mm = 10.14 TPI (25.4 / 12 x 1.183) |
thread depth | ~1.13 mm |
form | single-start, right-hand, ~69.4 deg |
gender, tub side | male |
thread length | at least 12.6 mm, about 5 turns |
where the face lands | 57.7 - 59.4 mm, a 0.88 mm wide band |
The 69.4 degree flank angle is not a typo. This port is a 2.375"-12 UN scaled 98.5 % in X/Y and stretched 118.3 % in Z, and the Z stretch is what opens the flanks up - which is why an off-the-shelf 2.375"-12 cap does not fit it. The scaling is already baked into the files. DO NOT rescale them in the slicer.
