Custom 3MF Mounting Bracket Design

I have a clear set of precise measurements for a small bracket that will serve as mounting hardware, and I need it converted into a clean, printable 3MF file. Once I share the dimensions and a quick sketch, you’ll translate them into a sturdy, well-proportioned 3D model ready for ASA filament 3D printing The finished file should: • Follow my exact measurements without scaling • Include smooth, manifold geometry with correct wall thickness for printing • Be delivered in a single, watertight 3MF file (STL or OBJ exports as extras are welcome) I typically print in PLA with a 0.4 mm nozzle, so keep overhangs and tolerances printer-friendly. Feel free to design in SolidWorks, Fusion 360, or similar—whatever you’re fastest with—as long as the export is flawless. A quick turnaround and willingness to tweak once after a test print will be appreciated.
