This is a custom wall mount for my 2nd screen Dell P2417H (simmilar models with same stand will fit as well). It's a 24" monitor with pivot stand (can adjust up/down, portrait/landscape and tilt), but it doesnt suppport vesa mount (edit: this is wrong, it does support vesa, but then cant use pivot mechanism). I wanted it on the wall so I printed 3 parts out out of PLA. One part is screwed in the wall and the other one is securing monitor in place using zip ties. 3rd part is a small shelf that is mounted underneath (with original screw for monitor base), but its there mostly to provide a flat surface between monitor and a wall.
I've been using it (2 actually) for few years in old place and I love it. It can be a bit tricky to tighten zip ties, but its only done once anyway.
I'll upload files if someone needs them
Pivoting+tilting+swivelling VESA wall mounts are also a thing, so you wouldn't have needed to choose the display based on its stand
I personally wouldn't have risked my monitor on being able to design a part that is able to last just to save the few bucks a mount costs. So props to you, I guess.
Im aware all kind of mounts exist, my setup is made from parts I had at home (including monitor ofc). I didnt want to spend 50€ or more on decent mount for 140€ monitor, but I respect that most people would just buy off the shelf product. Just sharing what I think someone might find usefull.
Strength wise, Im not worried at all, but Im clumsy enough that one monitor fell and screen broke while moving last year (RIP)
