EA to Sega adapter clips for Sega Genesis cartridge cases by Timstuff

Last crawled date: 3 years ago

One of my favorite ways to acquire replacement cases for Sega Genesis games is to buy a job lot of sports games off of eBay, because they're cheap and usually include their cases. However, EA cartridges are a different shape, and while some EA games came with "universal" cases that could hold both cartridges manufactured by EA and Sega, many do not, and that can be frustrating if you're trying to source replacement cases from sports games.
I've designed this adapter piece to solve this problem. It attaches permanently to an EA case and turns it into a universal Genesis / Megadrive game case. Now all those EA sports game cases that were once useless for non-EA games can be used to hold whatever Genesis games you want.
Printing recommendations:
I used Hatchbox ABS with an enclosure and a bed heated to 110 degrees. I also used supports with no vertical separation layers. I used a 20mm brim and printed directly on glass using ABS juice to ensure there'd be no warping or shrinking. I highly recommend ABS since it is less brittle than PLA and will not warp if left somewhere warm like a hot attic.
To attach the clips to your EA sports cases:
1) Use sandpaper to roughen the surface of the case where the clips will be mounted, and roughen the backs of the clips (this will ensure a tight bond)
2) thoroughly clean the mounting surfaces with alcohol
3) Apply super glue or a strong 2-part liquid epoxy to the back of the clips on the roughened surface
4) place carefully on the case as pictured. Hold firm for about 30 seconds and then let cure. Several hours (overnight is preferable).
I have probably not seen every type of EA game case so you may need to cut the case a bit to make the clips fit properly, depending on what kind you have. As long as it ends up looking like the picture above you'll be good. I highly recommend dry fitting it with a Sega cartridge before you glue it into place.
I borrowed the clip design from Grantek's Genesis / Megadrive case replacement design and used it to design this. Enjoy!
