T-shaped motor shaft adapter

Create a high-precision, completely solid, 3D CAD model of a T-shaped motor shaft adapter centered on the origin (X=0, Y=0). The part consists of two co-axial, perfectly centered sections: 1) Upper Magnet Disc: Outside diameter 44.0 mm, total thickness 13.0 mm. 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 are arranged symmetrically at 60-degree angles to each other on a Pitch Circle Diameter (PCD) of exactly 32.0 mm. 2) Lower Extension Stem (Zapfen): A solid cylinder extending straight OUTWARD and downward from the bottom face of the main disc. This cylinder must have an outside diameter of exactly 16.0 mm and a prominent, clearly visible extended length of exactly 24.5 mm projecting away from the disc body to perfectly fit the aluminum collar. 3) Internal Shaft Bore & Drive Key: Inside this 16.0 mm extended cylinder, carve a central co-axial blind hole with a diameter of 10.3 mm and a depth of 13.0 mm starting from the very bottom face. Inside this 10.3 mm bore, integrate a solid internal rectangular drive key (steg) spanning across the bore. The internal key must have a thickness of exactly 5.8 mm and a vertical length of exactly 12.2 mm to slide perfectly into the 6.0 mm wide and 12.44 mm deep female slot of the 10.21 mm motor shaft for a secure form-locking connection. The whole body must be 100% solid with zero hollow interiors. Export as a STEP file.
