Photographic Background Stand

This is my first time creating a model. I would be happy to see your feedbacks and makes. I designed this model to use it during the photo taking process of my models at printables.com. The model's original size is for A4 paper. Here are the scales you should print the model at to use the following sized papers:

A3: %140 scale

A2: %196 scale

A5: %70  scale

This model is created by Stephan Sozkes.
