I want a specific way to mount these hexagons where the screw was inside the hex but a whole back plane wasn't added so I designed this. It also keeps you hexes 2mm from the wall but if that's not what you're looking for feel free to remix (I'm including .step files but if you'd like another, let me know and I'll see if OnShape can export it).

Here's the OnShape document if you'd like to copy it into your workspace and mess with it.
