Roller base

A component from the Construction plant and machinery pack, with named material slots for construction machinery paint, construction site dark, construction site glass, construction site rubber, construction site metal, construction machinery orange and construction site plastic. It measures about 1.92 m × 2.16 m × 2.70 m (W × H × D) and comes as high, medium and low detail files. Place it on its own, or load one of the 1 included assembly that use it.

The picture is a studio render. View in 3D loads the GLB files themselves in three.js; switch between high, medium and low to compare.

Included in Construction plant and machinery (£24), which contains 24 component models and 8 assemblies.

Load it in three.js

import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
import { MeshoptDecoder } from 'three/addons/libs/meshopt_decoder.module.js';

const loader = new GLTFLoader().setMeshoptDecoder(MeshoptDecoder);
const { scene: model } = await loader.loadAsync('models/construction-machinery-roller-base/high-construction-machinery-roller-base.glb');
scene.add(model); // 1 unit = 1 metre, origin at the mount socket
