How to make an Origami Dropbox, a cool paper gift box designed by José Meeusen

Are you looking for a paper gift box to put small gifts or candy? Try the origami Dropbox, a very beautiful and very strong origami box designed by José Meeusen. You can make this box by folding one square piece of paper, without cuts or glue. Follow the step-by-step instructions of this tutorial to learn how to fold the origami Dropbox.
José Meeusen kindly gave me permission to make a video tutorial for her dropbox origami model that she designed in 2014. José lives in the Netherlands, and Drop is the name of a very popular Dutch sweet, hence the name Dropbox. It is a very cool box with a very clever locking mechanism that makes the box very strong. In fact once folded, it's very hard to open the box again, so if you want to put something inside your box, don't forget to put it before you close the box!
José has drawn a diagram for the Dropbox model that you can find here: origami.plus/origami-dropbox
I slightly changed the folding sequence, and I didn't notice it when I made the video, but the resulting Dropbox is very slightly different from José's original model. In the page linked above, you can see the two versions side-by-side folded by José, and there is also a great suggestion from José to make the model easier to close by doing an additional pre-crease fold. So please check it out. :-)
To make the origami Dropbox, you will need one square piece of paper. Only one side of the paper will show in the final model. It's best if you use paper that is not too thin. José recommends thick paper of at least 120g.
In the video, I use a 20x20 cm (about 8x8 inches) square. I also folded some Dropbox boxes with 15x15 kami, but the paper is too thin and it is more difficult.
If you fold the Dropbox, please send me some pictures so that I can show them to José and display them in future videos!
Thank you very much José for making such a great model, sharing your diagram and giving me the authorization to make this video!
Happy folding everyone!
