Just got the Benchnuts from Carbon Method and they are really cool, but I wasn't crazy about the included holder.  They did include one and that's cool! So thanks Carbon Method! But I thought it just stuck out to much, so I wanted to make a low profile holder, and then one thing lead to another.  Mine includes space for all 8 nuts so you can fit 2 on each pillar.  Two screw holes to allow you to mount on the wall or workbench or french cleat. Then I added support for embedded magnets, 4 were added but I tested with 2 and it holds great!  But you can always add the extra 2 if needed.  Now they can attach them to my toolbox, storage rack, or even tools!

The magnets used are here:
