The prompt
Center a vertical cylindrical axle component as the main spine, attaching a spherical or cylindrical central hub collar near the top that features three angular slot cutouts tilted at a 35-degree pitch. Model three rectangular balsa-style blade panels as thin flat plates, inserting their root edges directly into those angled hub slots to ensure uniform radial spacing. Directly beneath the hub collar on the same vertical axle, extrude a small cylindrical basket or ring cradle designed to securely house the egg payload, keeping the overall center of mass low to maintain stable autorotation during descent.
