I found this component tester on ebay for about $13, so I came here hoping to find an enclosure to print to put it in. There are a few other boxes to print, but none for the EZM328 (at least last I checked a few days ago). So now there is.

Yes, I know, there are some issues with my print. I'm working that out.

The first print I did didn't fit, so I redrew it. It now fits, but I forgot the numbers. The file I loaded here has the numbers on it. I included a picture of the bad print so you can see what the numbers will look like on yours. I'm not going to reprint mine just for the numbers. I'll just put a sticker on it or something.

I'm sure there are better ways I could have designed this, but it works. The back edge of the circuit board fits into a channel in the box base. You then put a screw into the forward left corner. Then put the top on and install three screws in the bottom and one screw on the top that will go through the right hand corner and into the base. Eventually I will put some rubber feet on the bottom. There were only two available screw holes in the circuit board, so this is what I came up with. Feel free to change it if you want. For screw, I just used whatever scavenged screws I had.

Any normal print settings should work, but the top will need support.
