Make sure the angle of the tab is greater than 45 degrees so that you can easily tuck it under the other faces! After you print it, just fold along the lines that connect each plane to create your 3D model. This will give the printed version another surface to use for gluing or taping and make the model more secure. That’s it! You’ve successfully used the sketchup unfold tool and you now have a flattened version of your 3D model that you can print out! If you want, you can use the line tool to add tabs on the edge of your faces.
