If you want to showcase a 3D model on your website or simply need to view an STL file online, there are several easy ways to do so. Here's a quick guide to help you get started. First, you can use online 3D model viewers like Sketchfab or Cl3ver. These platforms allow you to upload your STL file and embed the 3D model directly onto your website, making it interactive and engaging for your visitors. Another option is to use a plugin or extension for your website platform, such as the STL Viewer plugin for WordPress. This allows you to easily integrate a 3D viewer into your website and display STL files with minimal effort. Additionally, some browsers support native 3D model viewing, so you can simply drag and drop an STL file into your web browser and interact with the 3D model directly. Whether you're a designer, architect, or simply want to showcase a 3D model, viewing STL files on a website has never been easier thanks to the variety of online viewers and plugins available.
