openGrid Multiconnect Nonrotating snap plus screw

This modification of a non-rotating multiconnect snap for opengrid allows the grid cell to be used as a multiconnect mount point and also as a mount point for a bolt or screw. This can be particularly useful if you need to use a snap instead of a corner screw mount and don't want to lose the use of the cell. And it's especially useful on thin strips of openGrid where no corner screw holes are even possible. I normally use corners to mount my grids, but often have to use snaps when I am aligning to metal wire rack shelving. And in those cases, a regular screw snap uses up the cell entirely. I'm kind of surprised I didn't think of this before, because I have put screws through hexkey-locking print in place multiconnect snaps before. The hole is a 4mm hole with a chamfer for a flat-head screw with up to 9.5mm head. This should be fine for most of the 4mm bolts with hex or philips heads which I use to secure grids. I also often use some 3/16" toggle bolts that are between 4 and 5mm and the
