I need a precise 3D model of a wall mount bracket that I can send straight to my FDM printer. The bracket must be designed for plastic and should already include properly-sized mounting holes so I can fix it securely to drywall with #8 screws. Key details you should know as you design: • Wall-mounted orientation, roughly 120 mm long but I’m flexible if a different footprint increases strength. • Plastic material, so keep overhangs reasonable and add fillets where high stress is expected. • Two countersunk mounting holes, 5 mm in diameter, spaced symmetrically. Please provide: 1. A print-ready STL. 2. The editable source file (STEP or Fusion 360). 3. A quick strength-oriented design note (infill suggestion or rib placement) so I can dial in slicer settings confidently. I will verify fit on a test print; once the holes line up and the bracket supports a 5 kg load without cracking, I’ll release final approval.
