Introduction

To protect my brand new GIZMO 2 board from the pointy and metal objects (and the rest of the mess) scattered around my desk, I decided to design a simple 3D printable enclosure for it, which would still expose all interfaces. I'm no professional designer, so it's more a functional enclosure rather than a fancy looking one

I took various measurements of the board, especially around the ports and started porting this to SketchUp.

Design

This is what the first version of the design looks like:

As I said, the focus is more on the functional side of things. The enclosure has following "features":

access to microSD card
1cm standoffs, allowing room for mSATA/mini PCIe device
opening for high and low speed card edge connectors
opening for all ports: power, hdmi, USB3, audio, USB2 & ethernet
removable lid with an opening for the fan

I've attached the SketchUp files to this post in case anyone wants to build further from this. After printing, I'll check which adjustments need to be made and

Print

Having finalised a first version of the model, I tried to print it. The heated bed on my Printrbot was barely large enough, but it fit.

I enabled support material when slicing the model because of the many openings. After printing, I was able to easily remove it using small pliers.

There was a little lifting during printing, so the enclosure isn't totally straight, but it's still functional.

Here it is, in all its glory:

Power, USB and Ethernet access is OK. HDMI and audio are a bit off. I'll have to work on that for the next iteration.

Hope you like it! Feel free to provide feedback on the enclosure or make your own based on the files attached.

A nice simple design, I like it... You have beat me to it I have been designing one using OpenSCAD and currently printing first prototype as I write this.

Hi Brian, thanks!

The more options, the better. Curious to see what you have come up with!

I will post full details when complete, my design is in three parts, a base, a middle and a lid that screw together. and all parts can be printed without supports. First minor problem I have found is getting to the power and reset buttons. Ok you can take the lid off and poke them with a suitable implement ( most fingers are too thick to reach the power button). I am going to see if I can design buttons in the lid that reach down to the PCB.

Looking at the GIZMO2 schematics it is also possible to add a connector to the low speed expansion port which has the power and reset signals that can be connected to external buttons.

I also plan to have the buttons rerouted and accessible on the case. Still doing some research on that though

One thing I should add, I am also doing the design work on the GIZMO 2 itself and the performance is good, not quite as fast at rendering as my 8 core 3.6 GHz 16 Gbyte ram desktop I will post some speed comparisons too at some point.
