Use it

Code for the specimen as it is set up above; it follows your knobs.

JavaScript

import { createAsset } from 'https://gaitkit.com/cdn/ammo-crate.mjs';

const ammoCrate = createAsset();
scene.add(ammoCrate);                      // rests on y = 0, front faces +Z

// 'lid' pivots on its hinge: -110° to 0° around x
ammoCrate.getObjectByName('lid').rotation.x = THREE.MathUtils.degToRad(-110);

JSX

import { useMemo } from 'react';
import { createAsset } from 'https://gaitkit.com/cdn/ammo-crate.mjs';

export function AmmoCrate() {
  const model = useMemo(() => createAsset(), []);
  return <primitive object={model} />;
}

GDScript

# Import ammo-crate.glb (download below). Moving parts are separate nodes, pivoted on their hinge.
$AmmoCrate/lid.rotation_degrees.x = -110

// Import ammo-crate.glb with glTFast (com.unity.cloud.gltfast).
transform.Find("lid").localEulerAngles = new Vector3(/* x: */ -110, 0, 0);

Prompt

Use the gaitkit MCP server: get_variant({ "id": "ammo-crate", "want": "default look" })
then place the result.
