Exanima, it's mostly a testing ground for a game the devs want to make around this concept.
It's a good time, and also exactly what I think you're looking for.
Not to bury the lede, it is a fairly full featured action game, but there's not really a story element at this stage. https://store.steampowered.com/app/362490/Exanima/
I know this is way later and doesn't really matter, but I really liked your idea and thought about it for a while.
I ended up coming up with this spring "quick caps" for quickly moving, rearranging, or de-tensioning them for maintenance and it has really improved how the whole boom operates.
Which is where I thought I was pulling inspiration from, though I'm sure I watched his gantry video and had it sitting somewhere in my mind.
I totally forgot he did basically the same thing hahaha.
The springs I used here might be a bit weak for a monitor, I think the long ones are four pounders.
But I don't know much about springs and I just got ones that looked right from Lowes :)
As far as tips from this build, being able to change configurations and adjust positions did a lot to shore up the gap between what I wanted to do and how little I knew about any of this.
Also, I'd probably do a 90 degree bend at the middle link.
The rods are 3/8ths inch and the bolts are 1/4 20 hardware, plus 4mm machine screws assembling smaller parts and as grub screws. I think it'll stay together fine, but there's enough load over a long distance that it does have a little sway and bounce after moving it.
Although, after a few seconds it settles and I haven't had any issues. I figure that my phone's video stabilization will filter out the small stuff.
Oh yeah, and I printed the components with an 0.8mm nozzle and 0.5mm layer height. They're chonky.
Originally I was using all four, but after working with it a bit and changing the springs orientations I found it worked well with just the one set.
I've left the other two in case I change my mind :)
Now you've got me thinking of some sort of quick release system for switching these in case I do want the lean direction to change.....
That would be super useful.
