Is the Drills 3D model free for commercial use?

Yes. It is free under the 1DesignTool 3D library license: use it in personal and commercial work — games, apps, websites, renders, ads and client projects — and modify it as you like, with no credit required. What you can't do is re-sell or re-distribute the file on its own or inside a model pack.

What file format is it, and how big is it?

A single binary glTF 2.0 file (.glb), 159 KB: 1,846 triangles, 5,538 vertices and 35 materials, modelled in metres at 2.8 m × 7.0 m × 6.7 m.

Can I animate Drills?

It ships as a static mesh. Its 11 named parts are separate nodes, so you can move or animate each one in your engine.

Which engines and tools can open it?

Anything that reads glTF 2.0. three.js, React Three Fiber, Babylon.js, Godot 4 and Blender import the GLB directly; Unity and Unreal Engine load it through their glTF importers. The snippets above show the exact code for three.js, React Three Fiber, Godot and Blender.

How was the Drills 3D model made?

Claude Code (Claude Opus 5.5) generated it inside 1DesignTool's 3D template from a written brief, then the design kit's checks verified the geometry and the GLB before it was published. You can make your own the same way with 1DesignTool.

Drills

A low-poly crawler drill rig for quarry blast holes. A yellow tracked machine with a rear power pack, operator cab and cyclone dust collector holds a tall upright feed mast on its boom, with a top-hammer rock drill, a rod carousel and a drill rod running down into a heap of cuttings.

How it was made

The brief given to 1DesignTool's “3D object” template:

Drills for the Mine and Quarry kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. This is one part of the Mine and Quarry kit (Low-poly style, flat-lowpoly direction): Rock, dust and heavy machines. Use ONLY the kit palette, by name: ochre #bd8728, slate #525e6f, machine yellow #eecd2b, rust #9b4427, ochre dark #7e5a1b, slate dark #323943, ochre light #d6a95c, slate light #7b8593, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `oreColour` (0–1, default 0.5) for the kit's "Ore colour" setting wherever it makes sense on this part, and keep that id.

Note: Size: 2.84 m wide (x), 6.72 m long (z) and 7.04 m tall to the top of the raised mast at the defaults; the machine body alone is about 3 m tall. The mast end faces +Z, and the origin is at the bottom centre, resting on y = 0. The exported model has 1,846 triangles in 35 meshes (merged per part and colour), with no animation clip and flat normals baked in (non-indexed). Every material is named exactly after its kit palette colour; 6 of the 12 kit colours are used, and oreColour can bring in others. The exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. oreColour works in steps and only colours the cuttings heap: below 0.2 slate light, 0.2–0.4 ochre light, 0.4–0.6 rust (the default and the GLB), 0.6–0.8 ochre, and 0.8 and up machine yellow. mastHeight (5–8 m), mastTilt (0–15° forward) and hammerPosition (bottom to top of the feed) rebuild the mast, boom cylinders, hoses and rod. Params change geometry only when the scene is rebuilt in the viewer; the GLB is baked at the defaults. Both extremes passed three-check: (8 m, 15°, hammer at top, ore 1) and (5 m, 0°, hammer at bottom, ore 0). glb-lint reports 0 errors and 5 heuristic warnings: material count and duplicate materials (one material per mesh), unindexed geometry (flat shading on purpose), sibling overlap (wheels and rails nest on the tracks on purpose) and scale (compared with the direction's 1 m reference). It also gives its standing 'no requirements contract' UNVERIFIED verdict. three-check passes 24 of 24 checks; its triangle figure includes the viewer's staging ground, which is not exported. plan-check passes except for its part-id regex, which rejects the hyphens that this library's slug-based ids need; the same plan with the slug de-hyphenated passes. The viewer renders at exposure 0.66 on a tinted ground disc; neither is part of the GLB.
