Multiboard magnet mount x2 strong

Remix of the Multiboard flat head bolt, small thread by including 3 magnet pockets for D6x2mm magnets. (same ones required for Gridfinity).This version is for those who require stronger magnet force, stack two magnets per pocket for total of 6 magnets.Works well for heavier metal objects pictured a large pair of scissors. The bolts will also perform their normal non magnet functions as per original design. Pause has been included in profile, just insert magnets and continue the print.
