Sega Mega Drive/Genesis case for Sega and EA-style game cartridges

thingiverse

I've been collecting some old Sega Mega Drive games but most of them don't come with cases. There are some mass-produced options for replacement cases but I don't live in an area where it's practical to get them delivered - they would end up being quite expensive with shipping so I've designed a simple 2-part plastic box that securely holds the cartridge in place which can be covered with a printed paper sleeve for shelf-display. Cartridges licensed or manufactured by Sega are a certain shape and fit sideways in the box the same orientation as the original boxes while the other popular style was designed by Electronic Arts and fit in the other set of clips. Accolade also made some carts that fit in the EA clips but there were a few other niche ones that may not work at all. I don't have access to any Sega-manufactured carts for the Japan region which are smaller but there's a good chance they'd fit in the EA clips since those carts were designed to be region-free. Printing tips: The box is designed to be printed extremely roughly with a 0.3mm layer height and the roughness covered up with a paper sleeve. The clearance between parts is 1mm on each edge so if you're printing in higher quality the top might be too loose. Print in PET-G or PLA - ABS is a challenge I haven't been able to master with this it curls too easily. Support is required everywhere on the base box not just touching the build plate - it's required above the printed base all the way up to the clips. The front back and wall thickness is 1.2mm so make sure your shell setting is at least 0.6mm but you still need set infill to 100% for clean interface layers. I've designed mouse-ears into the STL to combat curling - these are removed after printing by wiggling them back and forth to weaken them then bending to snap off clean up with a sharp knife. Requires at least an 8-inch build area 200mmx180mm After printing you will need to make some cover art. Start with a good scan or fanart from eg. The Cover Project Start with a good scan or fanart from The Cover Project copy the artwork for the spine and place it on the left and right of both the front cover and the back cover art print out the front and back cover onto high-quality photo paper fold the front cover's spines down and the back cover's spines up fold them over your printed box for reference glue the spines together to form a sleeve
