Sega had completely given up on the 32x by the time that they released the Model 3 of the Sega Genesis. Sega even went as far as to remove support for the 32x at the hardware level on the device. This printed adapter is made to mate the 32x to the Model 3, but to use the system in this way a hardware mod will be required to connect the missing lines. This can only be done on early versions on the model 3 so keep that in mind but you end up with a compact system that can play the entire Genesis/32x cart library. This guy isn't for the average users.
This is a two part print that requires no supports. The two parts attach together with 6 M2x6mm screws.
