    R23.9 + R29.21. THEN 2 FILLETS. BUT IT IS ACTUALLY NOT AS EASY AS ALL THIS. THE 2 RADII SHOULD ACTUALLY BE TO THE INTERSECTION OF THE FRONT FACE AND THE CONICAL FACES TAKING THE DRAFT ANGLE INTO ACOUNT FOR THE PLASTIC MOULD...

    I'D SAY R24mm AND R29mm WITH 2 FILLETS OF R2.5mm

    OH YES... AND THE LINES YOU SHOWED ARE JUST THE EDGES OF THE FACE. WHEN YOU RENDER, YOU SHOULDN'T SEE THEM. IT IS NOT A PHYSICAL EDGE.
