silica gel box (resizable)

I've always wanted to create a desiccant/silicagel box, that can be customized to any size and has a proper closing lid. Well.. here it is!! This box has a sliding lid which closes properly so your desiccant beats don't fall out.  On top of that, you are able to configure the length, width and height to your liking. You can do so by pressing the ‘customize’-button. The size of the box when customizing, are the outer boundaries of the box.
