T-shaped Rotor Shaft Adapter

Create a high-precision, completely solid, 3D CAD model of a T-shaped (mushroom-shaped) rotor shaft adapter centered on the origin (X=0, Y=0). The part consists of two co-axial sections: 1) Upper Magnet Disc: Outside diameter 44.0 mm, total thickness increased to 13.0 mm to perfectly match the motor side and fit deep 10mm magnets. On its flat top surface, it contains exactly six symmetrical blind pockets for magnets. Each pocket has a diameter of 10.2 mm and a depth of 10.2 mm. These six pockets must be arranged symmetrically at exactly 60-degree angles to each other on a Pitch Circle Diameter (PCD) of exactly 32.0 mm (leaving a solid protective bottom wall of 2.8 mm on the opposite side). 2) Lower Guide Stem: A solid cylinder extending from the bottom of the disc. Outside diameter must be exactly 13.2 mm to rotate freely inside the 13.9 mm homogenizer shaft hole. The total extended length of this stem is exactly 2.8 mm. 3) Inner Shaft Bore & Transverse Slot: Starting from the bottom face of the 13.2 mm stem, a central co-axial blind bore with a diameter of 6.05 mm and a depth of 5.0 mm extends up into the main disc body. Centered within this 6.05 mm bore, a rectangular cross-slot (quernut) with a width of exactly 2.7 mm, a total symmetrical length of 7.2 mm, and a depth of 3.5 mm from the bottom face is carved out to catch the drive pin. Crucial requirement: The transverse slot must be oriented such that it aligns perfectly with the solid gaps between the magnet pockets, guaranteeing zero geometric intersection. The whole body must be 100% solid. Export as a STEP file.
