Use it

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

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

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

// 'bag' pivots on its hinge: -4° to 4° around x
punchingBag.getObjectByName('bag').rotation.x = THREE.MathUtils.degToRad(-4);

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

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

# Import punching-bag.glb (download below). Moving parts are separate nodes, pivoted on their hinge.
$PunchingBag/bag.rotation_degrees.x = -4

// Import punching-bag.glb with glTFast (com.unity.cloud.gltfast).
transform.Find("bag").localEulerAngles = new Vector3(/* x: */ -4, 0, 0);

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