Towfish Tail Stabiliser

Create a single-piece, 3D-printable towfish tail stabiliser. Overall length 90 mm (editable), maximum outside diameter 220 mm. Front mounting boss: Ø83 mm x 40 mm long, concentric with the main axis. Add 2 circumferential O-ring grooves centred at 10 mm and 30 mm from the front face. Between them, add 6 radial Ø8 mm holes for bonded threaded inserts, centred 20 mm from the front face and equally spaced at 60° intervals. Behind the boss, form a hollow tapered centre body with 6 mm wall thickness, approximately Ø89 mm at the front tapering to Ø50 mm at the rear. Add 4 identical radial fins at 90° intervals, each 6 mm thick, joining the centre body to the outer circular cowl. Give fins a rounded leading edge and taper to a 2 mm radius trailing edge. Add smooth fillets at fin roots and where fins meet the cowl. Outer cowl: Ø220 mm, approximately 6 mm wall thickness, rounded front edge, slight rearward taper, and rounded trailing edge. Make all key dimensions editable/parametric and keep the model hollow and suitable for 3D printing.
