About this 3D model
Here is a page gate without writing (initial). It is possible to put several pages horizontally or vertically but also memos or various flyers. In order to have a stable door, fill it with sand or pebbles and then glue the bottom with a strong glue. I advise you to add non-skid pads under the door page not to do hockey;) I also made a customizable version with writing on the front of the bridge: Customizable page holder.
