I specialize in designing print-ready 3D models for FDM and resin 3D printing. I work daily in Fusion 360, use my own Bambu printers to test and validate designs when needed, and publish my own tested models on MakerWorld. This gives me a practical understanding of real printing constraints such as tolerances, wall thickness, print orientation, overhangs, part splitting, material behavior, and assembly fit, while helping me catch and fix potential issues early. I have strong experience designing practical assembly features such as snap-fits, press-fit connections, printable threads, screw bosses, standoffs, dovetails, slide-fit mechanisms, modular inserts, and multi-part designs that are made to print and assemble reliably. You can see examples of my print-ready design work through my MakerWorld page link, which is available in my portfolio below. Core services: - Product concepts and functional prototypes - Electronics enclosures and PCB/battery housings - Holders, mounts, organizers, accessories, and small product housings - Miniature designs, scale models, and simplified printable replicas - Snap-fit, press-fit, threaded, and modular assemblies - Modular product systems and interchangeable parts - STL/STEP modification and printability optimization - 3D models from sketches, images, PDFs, or rough ideas - Slicer-ready 3MF files, print orientation, and part splitting - Text, logo, cutout, and surface-detail edits I focus on reliable prints, practical assembly, and clear communication. If you want to take your ideas from concept to reliable 3D prints/CAD models, let’s talk!
