Sega never officially supported the mating of the 32x to the final installment of the Genesis. If you were to install the 32x on the Gen 3 you would run into the issue of the system toppling over anytime that you touched it. I set out on a quest to rectify the injustice to the Gen 3, as well as the CDX and give both consoles the love of the tender embrace of a proper 32x riser.
The first to be released is the Gen 3 riser: http://www.retrorgb.com/assets/3dprint/Gen3_32xRiser2019-04-29.zip
This comes in two pieces, the top interfaces with the 32x giving a nice flat surface for other systems to be supported (Mega SG). The bottom section is much larger as it extends to the surface that the Gen 3 is sitting on to provide more support to keep the system stable. Overall its an easy print, splitting it in 2 pieces means that it can be printed without any supports. There are screw holes provided to mate the two pieces together making it a solid part.
