Updated 3/21/25: added small inset in the top for the dimple in the slots to slide into.

Updated 5/16/25: new model/profile with snaps for full-size openGrid

openGrid is designed to use Multiconnect, however because the spacing is different between Multiboard (25mm) and openGrid (28mm) anything printed with Multiboard spacing cannot be used with more than one Multiconnect point. This is a snap which is offset by 3mm to compensate for that. Together with an un-offset snap, you can use up to three rows of Multiconnect to hang your Multiboard-spaced accessories. For simplicity, I modeled this as a single piece rather than separate screw and snap. I also tried 6mm (allowing 5 rows) however there is a small overhang. It is probably possible for someone to tweak the model to make it work though.

To use, put down an unoffset multiconnect and put the 3mm offset multiconnect on one or both sides, oriented towards the first piece. I used this to replace some Multiboard underware with openGrid Lite underware while keeping my accessories.
