This is a case for a PSX SNAC for the MiSTer Multisystem Console. 

Requirements:

• 2 x PSX Controller / Memorycard Ports, I harvested mine from a third party Multitap from MAXPLAY, but an official Multitap should work too
• 8 x M2x8 screws
• 8 x M2 nuts (optional)
• 1 x PSX SNAC (https://github.com/blue212/SNAC-PSX) - just search for “PSX SNAC” at eBay
• Solder iron, solder tin, enameled wire, a few cables and pin headers
• 1 x print of psx_snac_case
• 1 x print of psx_snac_case_backcover
• 1 x print of psx_snac_case_clamp1
• 2 x print of psx_snac_case_clamp2

I never printed the final version of the back cover, I hope it fits properly.

Description:

• Print the files. It is a really tight fit and you should be sure everything fits before you solder
• Testfit the ports. The fitting is tight and I needed to cut a tiny bit of the ports to make it fit
• Optional: Insert the M2 nuts. Insert the nuts into the slots and screw in a M2x8 screw to pull the nut into its slot. Remove the screw again. 
• Mount the side clamps (psx_snac_case_clamp2). You still should be able to get the ports in and out
• Remove the composite port from the SNAC adapter, I also cut away the part of the PCB where the port sits, it might by hard to fit in the adapter otherwise
• Testfit the hardware and make a plan how to connect everything. Have a look on the photos to get an idea how I did it. 
• Solder the adapter according to this thread: https://misterfpga.org/viewtopic.php?t=5232
• Mount the Ports and the hardware, I added cable ties (and a bit hot glue) to the cable to make the tight bends I needed
• Mount the center clamp
• Mount the back cover
