Need banana for scale.

What’s their intended holding purpose?

Hopefully the rack is mounted directly into the studs or concrete. I’ve seen them crush gypsum between the stud and paint too…

I’m not much help, but they all suck. I’ve bought probably 2k worth of universal sliding rails to attempt with various servers. I don’t know why but none of them fit properly. None of them slide properly. They are all just annoying. I gave up with them. I bought the OE sliding rail kits for my various servers and magically everything works perfectly.

For servers where I want to move them in and out but don’t want sliding rails, I just buy those universal L bracket type mounts. The servers slide well enough on them, they’re just powder coated bent steel. And a single screw from the front panel into the rack keeps it secure enough since the weight is being held by the support, not its own ears.

I have the spheres. I of course, for science…, tested one over a small garbage can fire I set purposefully. It worked way better than I thought it would. I have one in my server racks, multiple ones over my mining equipment, and did have one over my older 3d printer. The miners are the only thing I think would ever actually catch fire.

You use a real CAD program. The free tools can get you pretty far and are great for basic stuff. But as you’re learning, once it’s not basic, it’s not a problem for a free shitty tool to solve.

It becomes a problem for a very expensive shitty tool to solve, like Solidworks.

Designing those things that slide into each other and everything on non perpendicular planes is child’s play in SolidWorks. The slide in feature assuming they are mates is basically 3 button clicks and 10 seconds. Bam, done. Weird angles and planes, super easy.

You pay dearly for such ease. But that’s how it’s done. If you can’t afford a trial or a student copy or a used copy, then there are ways. But a SolidWorks DVD from 15 years ago will do everything you want it to. CAD doesn’t change much. And if you don’t need super fancy 3D photo realistic renderings and the ability to import PCBs and thermodynamic simulations, than a 15 year old almost free copy of a powerful tool will beat any modern free tool.

I have all my houses completely smart outfitted. Except the bedrooms. Yes you can have a wireless switch control a wireless light. I do that everywhere because then nobody gets confused and flips a switch.

I haven’t touched a light switch in years. Every room has mmWave sensors either in the ceiling or on a shelf or both. You walk in, lights go on. Leave the room for a minute, lights go off.

The problem is a bedroom where that doesn’t work. When are lights on? When you’re in the room and not in bed? Ok. That’s a lot more complicated. Get up in the middle of the night to pee, now the whole room is blasting light and waking up your partner. Reach for your phone, detected as motion outside the bed, inter of a tip lights come on. It never seems to work because too many variations.

Because of that I keep a remote by the bed. The light switch works, the phone apps work, the voice assistants work, all as usual just no automatic sensor. Then in addition the remote by the bed can turn the lights on full, one bulb dim, or off. One for each side.

Those brother printers are like $80 or something stupidly cheap. The heatshrink tubing labels a few bucks more. Totally worth it. Swap out normal labels and then label your hard drives, your servers, your disk bays, etc. A basic label maker is a life changer and will last forever
