Pistol-Grip IUD Handle Assembly

Create a compact, ergonomic, pistol-grip-shaped medical-device handle, not a rectangular box. The form should resemble a small handheld surgical tool: a rounded horizontal upper body with a downward-angled grip beneath the rear half. The upper body should be approximately 100–110 mm long, 30–35 mm wide, and 25–30 mm tall. Add a comfortable angled grip approximately 65–75 mm long, angled 55–65 degrees downward from the upper body, with a rounded oval cross-section sized for one-hand use. Use smooth transitions, large fillets, and a streamlined prototype appearance. Do not create a plain rectangular enclosure and do not place exposed screws on the visible exterior. At the rear of the upper body, create a fully open rear-facing loading slot/channel for a separate existing IUD inserter and slider. The channel must be open with no door, lid, clip, latch, or cover. Use an open U-shaped channel with shallow guide rails and an internal front stop. Start with a 14 mm wide by 10 mm high channel. The IUD inserter slides in from the rear along the long axis of the top body. At the front of the upper body, add an externally threaded cylindrical outlet for separate tubing. Outlet outer diameter: 11 mm. Use M11 x 1.0 external threads, approximately 10 mm long. Do not model the tubing, orange clamp, sounding tube, or IUD inserter. Place a thumb-operated handwheel on the outer top side of the upper body, near the junction between the upper body and grip. Wheel diameter: 24 mm. Wheel thickness: 6 mm. Add shallow ridges around the rim. The wheel turns a transverse internal shaft. The shaft is a two-groove cable drum for two steering strings. Include two side-by-side string grooves, each about 1.3 mm wide and 1.2 mm deep, separated by a raised center flange. the strings will be Routed one through a left internal channel and the other through a right internal channel. Keep both string paths isolated from the central IUD-inserter channel. Include two small mirrored flexure tension arms or spring tabs to take up slack in the string that loosens when the opposite string is tightened. Internally, separate the design into: a central open IUD-inserter channel; left and right string-routing channels; and a side wheel/drum compartment. Use a two-piece clamshell construction split along the centerline, and rounded internal string guides. Keep the geometry simple, functional, manufacturable, and suitable for 3D printing. do not use screws or anything and make it splitable down the middle. use the image as a reference.
