Raspberry Pi 1B Retropie case

I wanted to learn a bit more about Raspberry Pi's as I have never done anything with them. I found a used RPi 1B on eBay for $30 AUD and decided to have a crack at it. I was going to try Octoprint but found out I needed a newer pi so turn it into a retro emulator with RetroPie.

Its just a simple case, with slots for the power, headphone jack, SD card holder and the USB and Ethernet ports.  I tried to emboss a skull on the frame but my printer didn't really like the grey PETG i was using so I've included a blank one as well. 

The screen frame and case uses 8 x M3 bolts and the pi is mounted with 2 x M3 screws. I used cap head bolts for the looks.
