MultiBoard mount for heavy duty Kobalt shelving

I've removed the mounting holes in the MultiBoard mounts and added the Kobalt mount.

I'm including the “old” 8mm and the “new” 6.25mm standoffs.

I've found that leaving 4 empty MultiBoard snap holes between mounts seems to line up fairly well with the Kobalt openings.

Printing with the MultiBoard standards works well, no supports required when printed with top down.

License also includes MultiBoard's terms.
