4mm Hex Bit Holder with Screwdriver Mount

I needed a 4mm hex bit holder for my shop, which currently uses Sy's Peglock system, so I created this model. This model will hold 20 4mm bits and the screwdriver. The screwdriver opening measures 0.6 inches, and the hex openings measure .17 inches, on the model, and my bits measured just over .15 inches. This tolerance allows the bits to slide in and out easily. My Printer Settings (Bambu P1S) Rafts: No Supports: Yes - Tree(Auto) / 30 Threshold Angle Resolution: 0.2 Infill: 15% Filament material: PLA
