Request for LattePanda Sigma UPS Module 3D CAD Model

I am looking for a 3D CAD model of the LattePanda Sigma UPS module for use in a mechanical enclosure/project design.

In particular, it would be very helpful if the model includes:

The four battery-slot compartments/locations

Screw holes and the screw-thread geometry, if available

Accurate external dimensions, connector locations, and mounting-hole positions

A STEP, IGES, SolidWorks, Fusion 360, or other commonly used 3D CAD format would be greatly appreciated. If a full model cannot be shared, a dimensional drawing or mechanical specification sheet would also be very useful.

Thank you in advance for your help.
