openGrid Multiconnect rails

Thanks to https://www.printables.com/@DavidD for his great additions to Multiboard and his own Design openGrid. I wanted to have Multiconnect rails that fit openGrid usable either as rail connector or as french cleat. And here they are. Currently it's provided in the lengths 1, 2 and 3 (briding 0-2 empty grid slots inbetween). The rail has the exact size of the Multiconnect head and acts as a linear extension. I am using it with openGrid light but I guess it should work fine with the regular openGrid. No special print settings are needed - mouse ears can help in avoiding the sharp ends to warp from the printing platform.
