Alternative ways to build a development board enclosure?

I’ve been working on a development board for a while now. To finalize the product, some people recommend printing a case (I don’t have a 3D printer). Do you have any other suggestions (the most fun ones are also welcome), or should I invest in this type of machine?

Please give me as many practical ideas as possible, I’ll make my selection later.
