Wall-Mounted 1/4" Hex Bit Holder (30 slots)

Create a precise, fully 3D-printable wall-mounted screwdriver bit holder based on the attached reference image. Design requirements: 1. Three horizontal rows, with exactly 10 slots per row (30 slots total). 2. The holder must be angled slightly backwards, similar to the reference image, so the bits stay securely in place. 3. Each slot must have a HEXAGONAL internal shape, NOT a round hole. 4. The internal hexagonal sockets must fit standard 1/4-inch (6.35 mm) HEX screwdriver bit shanks. 5. Use a snug fit with approximately 0.2–0.3 mm clearance, suitable for FDM 3D printing. 6. Make the hexagonal sockets deep enough to securely hold long screwdriver bits and adapters. 7. The hexagonal shape must continue inside the socket, not just at the entrance. This is important to prevent the bits from rotating. 8. Add a small chamfer at each entrance to make inserting and removing bits easier. 9. Include a strong flat back plate with two mounting holes for wall screws, one on each side. 10. Add sufficient wall thickness around every socket to prevent cracking. 11. Design it as one solid printable part, without unnecessary supports. 12. Use rounded external edges and a clean, professional workshop-organizer appearance. Important: Do not create circular holes. Every bit holder must have a properly sized internal HEXAGONAL socket. Generate an accurate parametric CAD model and export it as a downloadable STL file. Also provide a 3D preview and the exact dimensions of the sockets.
