In the past few years, we have covered a whole host of WordPress plugins for 3D printing shops. Woo 3D Viewer is designed for WooCommerce stores. It is a 3D product viewer that supports STL and OBJ files. You can customize color, transparency, and shininess for your models.
The pro version of this plugin allows you to convert models to animated GIF, Webm and PNG format. It also supports variable products. You can change resolution, shading, rotation, grid, and other options from the back-end.
