semi-circular card organizer 3d model

Create a precise, functional, 3D-printable CARD ORGANIZER consisting of ONE SINGLE FLAT SEMICIRCULAR PLATE with four integrated card grooves. IMPORTANT: The main body MUST be a true semicircular plate. Do NOT create a rectangular tray. Do NOT create a rectangular base with rounded corners. Do NOT create a fan-shaped rectangle. Do NOT create a circular tray. The outer silhouette of the main plate must be exactly a HALF CIRCLE. The straight diameter edge of the semicircle must face the user. The curved edge of the semicircle must face away from the user. ================================================== CARD DIMENSIONS Each card has: * Length: 120 mm * Width: 72 mm * Thickness: 0.3 mm The organizer must accommodate four cards with these exact dimensions. The card slots should have enough clearance to allow the cards to slide in and out easily. Do not design a 0.3 mm wide slot because that would not be practical for FDM printing. Use shallow recessed grooves approximately 1.0–1
