DIY Arduino Cases You Never Knew Existed

There are sure a lot of varieties of Arduinos out there but there may even be more of a variety when it comes to Arduino Cases. Let’s take the most popular Arduino form factor, the Uno. Below are a handful of unique cases for the Uno-sized boards.

We’ll call this one robust. Although it is 3D printed, its intent is to be extremely protective of the inhabitant. Some extra thought went into this case, no tools are needed! After the Arduino snaps into place, so does the cover. There is an access door to get the input/output wires to the free world. [Megaduty] suggests that this contains $0.10 of plastic. Not a bad deal.

By looking at these photos you may think you’d need a laser cutter to make this stylish case. Not so! [Jason] sketched out the design on lexan, cut it out with a jig saw and then heated the material to bend it around a wooden form.  It’s worth noting that the top of this case has openings so that a shield can fit onto the Arduino while it is still in the case.

If your Arduino project is using a SainSmart LCD keypad shield for the user interface then this case will surely put a smile on your face. The holes line up with the buttons on the SainSmart shield. In addition to the case, the buttons are also available for download and printing. Screw holes are provided to allow secure attachment between the shield and case. All you need is a 3D printer to get going with this project. It comes in any color as long as it’s pink!

This one is similar to above, it is 3D printed and designed for an LCD/Button Shield, but this time for another shield configuration. As you can see it has integrated flexible tabs that allow access to the shield buttons. What you can’t see from this photo is that it is mounted to a standard 4×4″ electrical box available from any hardware store. A standard electrical box is deep enough for the shield and an Arduino. Extra-deep boxes are available in case you need more room.

What came first, the Arduino Case or the CNC Router? A pretty cool DIY CNC Router was responsible for making this case. An Arduino running GRBL controls the CNC Machine, which moves a spindle that, in turn, cuts pieces out of wood, and those pieces of wood are assembled to form a case that holds the Arduino that runs GRBL…… your mind was just blown.

Are the above cases not good enough for ya? Maybe they don’t have enough features, or are only good for finished projects. If you are interested in taking your perpetual Arduino project on the road then pay attention. This case not only holds an Arduino and breadboard, it has two drawers for your components. If the breadboard and one of the drawers are removed, the closed case will even fit an installed shield. Download the STL files here.

This list wouldn’t be complete without at least one (or two) extremely inexpensive case options. Here we have a Lego-based enclosure. What it lacks in style is made up by its zero-cost and minimal effort required. It does what it was made to do.



by [Allan],  Cardboard Insulator cardboard arduino case

I’m not sure we can call this a ‘case’ per se, it’s just a piece of cardboard tied on to an Arduino through the mount holes. [Allan] had to do this to prevent the contacts on the underside of the board from shorting by way of typical workbench clutter.


If there’s a sweet case out there that we’ve missed, let the other readers know in the comments. Or, maybe you’ve made your own specialized case, document it somewhere on the ‘web and let us know.

  1. Usually I just put a drop of hot glue on all four corners and glue a flash card to the back then trim it with scissors. If I need to remove the hot glue, put of drop of rubbing alcohol on it and the glue falls off.

  2. Usually I’ll tear off one short side of an altoids tin and mount with double-faced tape. It’s not actually a particularly good mount (particularly in variations where something then needs to be mounted on the top of the box — like, for instance, basically any circuitry), but it’s cheap.
