The prompt
1 Design a circular flange, 66mm outer diameter, 6mm thickness. Add a central through-hole of 20mm diameter. Add a bolt circle of 4 clearance holes, 5.5mm diameter each, evenly spaced on a 45mm pitch circle diameter, first hole at 45 degrees. On the bottom face, add a counterbore around each of the 4 holes: 9.5mm diameter, 2.5mm deep. Material: Aluminum 6061-T6. 2 Design a cylindrical body, 66mm outer diameter, 8mm thickness. Add an internal pocket (cavity) on the top face, 34mm diameter, 5mm deep, centered on the part axis. Add a rectangular O-ring groove on the top face, 3.4mm width, 1.9mm depth, forming a circular channel with 42mm pitch diameter (centered on axis). Add 4 threaded holes M5, evenly spaced on a 45mm pitch circle diameter on the top face, first hole at 45 degrees. Add 6 threaded holes M4, evenly spaced on a 45mm pitch circle diameter on the bottom face, first hole at 15 degrees. Material: Aluminum 6061-T6. 3 Design a flat ring (annulus), 66mm outer diameter, 42mm inner diameter, 4mm thickness. On the top face, add 29 identical counterbore-style ball pockets, evenly spaced on a 56mm pitch circle diameter: - entry diameter 8.5mm - necking down to a retention throat of 5.8mm diameter at 3.2mm depth - throat continues for an additional 1.2mm depth (total pocket depth 4.4mm) Add 6 clearance holes, 4.2mm diameter, evenly spaced on a 45mm pitch circle diameter, first hole at 15 degrees, aligned with the body's threaded holes. Material: Aluminum 6061-T6. 4 Design a small cylindrical fitting, 16mm hexagonal head across flats, 8mm length. Add an external thread M10x1 on the full length. Add a through-hole of 8mm diameter along the central axis (vacuum passage). Material: Aluminum 6061-T6.
