The Working Spec Model viewer app is used in conjunction with QR codes placed on Marketing Material and Product Packaging to easily relay assembly instructions for a product.

The instructions come in the form of an animated 3D model which can be viewed from any angle to get a better idea of how complex components fit together in an assembly sequence.

You can use our browser app to scan WorkingSpec QR codes and view the interactive 3D models.

You can find demo pages to test the app over at or view more models by selecting "Models" from the top menu bar.

This app requires an active connection to the internet via WIFI or a Mobile data provider in order to function correctly. It is the responsibility of the end user to maintain the internet connection.
