Woodworkers of MCB: terminology?

[Deus Machina]

I need spacers for my shelf. I don't want replace it because it has worked and fit perfectly for my purposes, and I'm just trying to find the best adjustment here.
It's an old-school pillar-and-board style. Cylindrical corner posts, drilled and threaded at the top and bottom, with the studs running through boards between the pieces. So it's open on all four sides, and has a usually-generous 14.25" between.
Except a PS5 is 16".
So I need... spacers? Risers? I don't know what to call them, so my search has ended up fruitless.
Basically I just need eight 7/8"-thick discs with a whole through the center. They will get painted or stained to match, as fits material.

Presumably you're not addressing the carpenters of McDonald's so I have taken the liberty of correcting the typo in the title 😁

[Deus Machina]

No idea how I fumbled that, but yes.
Of course, I could contact the carpenters of McDonald's for some really... interesting answers.

That would be something I'd just slap on the printer, if it were me

[Deus Machina]

That was my first thought, and I probably will. But long term, I'd like it to match.
And if I need to thread it, I don't trust the plastic much for that.

3D printing...you guys crack me up. Why spend 10 minutes cutting up $1 worth of wood when you can spend all day waiting for a robot to make them out of something more expensive?

[Rainmaker]

Its more like:
5 minutes in CAD
4 hours of walk-away-and-do-something-esle printer time
$5 of printer filament (if that)

Just sayin.....

[Deus Machina]

I figured, in the long term, I'd prefer $5 on ebay and an afternoon of staining, drying, and reassembling...
But I don't even know what to buy. So 5 minutes (seriously, both CAD and slicer together) and then playing the new PS5 while I wait.

[SignOfZeta]

Five minutes? I literally don’t believe you. It’s clearly taken the entire five minutes of forum time already.

Most home improvement stores will sell 0.25 to 2 inch diameter dowels. I’d get one, cut cylinders to length, and drill through the centers. Then grab a stain that should match, dunk em, and wipe the excess off.

Yup. Except I don't have a workshop or half my power tools any more, it would take me all day cutting eight, then getting sets of 4 even and straight.
Just hoping to spend an extra couple dollars and save myself a lot of trouble.

What about something that already has a hole in the middle? Like PVC, or similar?

The issue being that the studs through them are only 3/16", and the posts are 1-1/2" or something. So not easy to find that, and I'm hoping for something that matches eventually.
For now, black PETG will make do. It's dark oak, it'll be fine for a while.

Is raising the shelf gonna run it into the bottom of the cylindrical post above it?

They're separate pieces. Post-shelf-post, the posts have screw studs in the ends and the shelf has a hole for it to pass through. So as long as the studs are long enough or I can find longer ones, I can assemble them however I want.
For instance, I just attached the bottom two sets of posts straight to each other, sans shelf, for my PC.

Maybe a picture? if I haven't lost my mind I believe the piece you are referring too was commonly known as a "standard."

Yeah, different kind of shelf. Unless Google is failing me again.
Excuse the mess while I figure things out and rearrange.

Got some 18mm (bit less than 3/4") Baltic birch plywood on the big cnc router at work today. And plenty of leftover scrap on the programmed pattern. Might be able to sneak in a few disks. Just need final confirmation on dimensions.

[Fubarius]

And in the cabinet biz what you're looking for is called a Standoff. That usually has a threaded stud on one side, and a matching threaded hole on the other.

[Deus Machina]

Thanks.
Tested a couple printed spacers, need too much extra for existing hardware to reach. Found a couple bits on ebay that I will get to work.
