Had a bunch of Wyse thin clients sitting on the floor and needed to get them up and out of the way. Could I have purchased something to accomplish this? Why yes, yes I could. However, I decided to throw something together and print these out and they've worked great. They have a 3/4 channel in the back for a Velco strip. Drive a screw through that and everything is tight and snug. All screw holes are for standard drywall screws and are countersunk to keep from scratching the device. Also has a movable mount tongue to accommodate different device sizes.
I used PLA with a 20% infill and no tops or bottoms - except for the tongue although the next prints I'll skip that as well. Very sturdy, no issues.
