sci-fi energy blaster 3d model

Create a highly detailed original sci-fi desert scavenger energy blaster prop as a single solid printable model. The design should feature a long energy barrel, exposed pipes, bolts, cables, vents, cooling fins, wrapped grip, and rugged salvaged technology with a worn desert appearance. It should look handmade from scrap metal and advanced technology. This is a non-functional display prop only. Create an original science-fiction design that does not copy any real firearm or existing movie prop. The entire model must be a single printable piece that fits inside a 220 × 220 × 250 mm build volume for a Creality Ender 3. Optimize for FDM printing with watertight geometry, 2.5–3 mm wall thickness, clean topology, minimal supports, no floating parts, and printable overhangs. Export as one watertight STL file. Style: realistic hard-surface sci-fi, ultra-high detail, movie-quality, clean geometry, ready for sanding, priming, and painting.
