What you get

• .blend (Blender 5.1, Cycles): every model is an asset — drag it from the Asset Browser, it lands on its base. Catalogs by category.
• FBX, OBJ, GLB: one file per model, plus the whole kit in one file.

Scale and materials

• Real-world scale in millimetres, clean English names.
• Every part is built from its ISO or DIN table: threads, hex sockets, Phillips recesses and strength-class markings are actual geometry.
• Each screw pivots on its seating plane, so it drops straight onto a hole.
• Finishes in the .blend are procedural (clear zinc, black oxide, stainless, brass, white nylon): no textures to relink.
• UVs on every part, PBR metal/roughness materials.
