I need a 3D designer for a prototype or product that I can print on my 3D printer (Bambu Lab A1 Combo). The object should be medium-sized, fitting on a standard desk, and the design must incorporate high detail with complex and fine features. The end goal is to have a fully printable 3D file ready for production. Please ensure the design is optimized for 3D printing. I'm looking for precision and quality in the final deliverable.
