What are free tools for light bottle 3D models?

Free tools for light bottle 3D models typically include Blender (open-source, with full modeling and lighting features) and SketchUp (user-friendly, plus free plugin support). Blender excels at detailed work—like adding glass textures or LED glow—while SketchUp is ideal for quick basic shapes, with plugins (e.g., Lumion LiveSync) to test lighting. For hobbyists or students, these tools let you create custom light bottles for free. If you’re new, start with SketchUp to learn basics, then try Blender for advanced lighting—both have free online tutorials to guide you.
