openGrid side panel snaps for AMS Riser V2

Slicer hacked together riser v2 side mounts with snaps. No measuring was involved, just importing geometry and lining it all up.The distances don't match up exactly but they're close enough that there are no modeling issues. Absolutely won't fit if assembled backward though. The snaps should be slightly farther apart than the the riser attachment points. If something doesn't fit then try it the other way around. They ended up 8 grids wide so plan around that. Any grid above the level of the snap blocks the spool holder storage (if that matters to anyone). I have four pieces of 5x9 grid mounted in the photos with the full board. KYZ snaps were selected for printability and ease of use in my first version. I printed mine in PETG to hedge against creep. They printed well first attempt so I don't anticipate any difficulty for anyone. For completeness and in case I wanted them later I also made reverse threaded snaps for multiconnect support.
