The 32x is not officially supported, or supported at all on the Analogue Mega SG. There have been rumors about the support eventually making it with the addition of a DAC that outputs RGB. If it ever comes I figured I would just adapt my other 32x risers to work with the Mega SG.
This is a two part print that doesn't require supports. The two halves attach to each other with 6 M2x6mm screws.
