Summary

This a super simple rack shelf I designed real quick in Tinkercad for my NUCs. There's only two pieces because the edge pieces are reversible, so print two of them. You'll need rack ears as well. I figured metal rack ears would be much sturdier than printed ones.

Originally I designed this with holes matching a particular set of rack ear, but after having to use a different set I got rid of the mounting holes in favor of just drilling them afterwards to match whatever rack ears you have on hand.

It takes 4 M3 bolts to assemble the pieces together, then another 8 M3 bolts to attach the rack ears. So 12 total, plus nuts.

You'll need two more M3 bolts per NUC if you want to fasten them to the shelf. Or you could just leave them loose.

I have 2 NUCs so this worked perfect for me. The 2 NUCs mount on to the side pieces and then theres room in the middle for accessories.
