Summary

Prompt

Make a rectangular block 40mm long (X) × 30mm wide (Y) × 20mm tall (Z), centered at the origin BEFORE any rotation. Then rotate the block about its center by 30 degrees around the Z axis (the rotation matrix Rz(30°)), and after that rotate again by 15 degrees around the X axis (Rx(15°)). Both rotations are about the origin, which is the block's center. Output a single solid.
