M42x0.75 thread and 30mm o.d. are as advertised,
but i.d. is far too loose for 23.2mm oculars:

... corrected by shimming i.d. with bits of HVAC pressure-sensitive aluminum tape.

Celestron NexYZ 3 axis Universal Smartphone Adapter

  • rack and pinion XYZ adjustments
  • spring-loaded smartphone clamp
  • spring-loaded and thumbscrew-secured eyepiece clamp with 2 bushings

While Z and coaxial XY controls work well, the holder sags:

wanting about 8mm shim between smartphone back bottom and holder
for camera to peer straight into eyepiece.

Blame sag on largely polymer construction and corrugated spacer (green arrow):

.. included to compensate for clamp intended mostly for digiscoping,
where sag may be less problematic with nearer vertical smartphone orientation.

An alternative to consider is the less expensive but aluminum SVBONY SV214,
which seems a near copy of the well-regarded tridaptor

with a clamp intended for diameters covering microscope oculars.
