How to make US Army wooden crates quickly

Whatever it is for a diorama or storage on a vehicle, crates are always welcome. 

Like this one:

I used balsa wood to create them.

Model 1:

Out balsa strip of 10 mm X 2 mm we will create the box itself. 
Out of 4 mm X 1 mm we will create the lid and bottom.

   
You need to cut first 2 boards of 35 mm length and 2 of 16 mm.

Once done, glue them with cyanoacrylate glue (super glue)

Take great care to get the corners squared as well as getting it flat.

While it is drying, we can now work on the lid and bottom of our boxes.

For this, out of the thin balsa you must cut 4 boards of 35 mm length x 4 mm. Sometimes it is hard to get 4 mm strips, so you can use wider ones and cut them to 4 mm.

I'm using a piece of 1 mm/1 mm to get the lid centred allowing me to set the crate in open or closed position.

For the bottom it is better to glue them directly. 

ET VOILA!

It took me between 4 and 5 minutes to do one, so that’s why I’m saying it is quick.

Of course now you can weather or paint them and get a result like this.

So what I’m doing is, when I have some minutes left in a day, I’m making one or two of them.
