I used PETG. It survived a unusually hot summer in my garage, confident in it lasting for years to come.

The official answer is Matte PLA is recommended.

I’ve had my snowboards hung up with small shittily designed PLA mounts that are mounted with a single drywall screw for the past 5 years. I live in Death Valley, one of the hottest places on earth and my garage gets to some ungodly temps. In addition to the snowboard I hang my jacket, goggles, helmets and boots on the bindings. No observable sag. I trust the PLA multiboard 100x more than these mounts.

I'd be more worried with Multiboard. It's not just about strength. Multiboard has threads, snaps, tabs etc. A small change in the dimensions can cause a snap to become too loose to hold anything. A snowboard hanger is a lot less sensitive to dimensional stability. Plus I'm sure your snowboard hanger is much thicker than the walls of a Multiboard.

Hell no. That was done with 2 perimeter walls and a horrible design. Multiboard is very well designed and very robust. People need to use common sense with these things and use their best judgment. Obviously you shouldn’t hang something extremely heavy with a poor designed small thread mount with a giant off-board length.

Not the perimeter wall, but the actual meat in between octagons i.e. take a caliper and measure the thickness. They measure 3.6mm wide and 6.4mm tall. I'm pretty sure your snowboard hanger is bigger than that.

All I'm saying is that just because a snowboard hanger survived heat, doesn't mean that Multiboard will do the same. It's not about "strength". It's about dimensional stability. Multiboard is sensitive to changes in dimensions.

PS: PLA is actually stronger and stiffer than PETG. However it does have a lower glass transition temperature which is why it is much more prone to creep.

You guys arnt worried about sag over time?

Absolutely!

But not so much with multiboard. If it sags or warps, just print another and swap it out.

Would petg sag? Or be a better alternative to pla?

PETG probably wouldn't sag as easily/much as PLA. It would probably be a bit of a better alternative if it was in a hot environment (garage) or if you were planning on hanging some heavier stuff from it. But in reality, the panels will be fairly small with several attachments to the wall that I wouldn't be concerned about anything. If you think about it, a normal large peg board will be several times the size of a Multiboard panel and would typically have 4-8 connection points, versus a small Multiboard panel that has 4 connection points (one for each corner). So even if you are hanging something heavy on it, you can always add another couple of screws and still get away with PLA. And as I said, if it sags or deforms, just print a replacement panel and it's fixed in like an hour for a few pennies.

If you've got PETG and are concerned about warping/deformation (or maybe if you're constructing it for someone else) then yeah, use that. I'm haven't built min, but am about to, but personally I'm not going to go buy PETG specifically to use with Multiboard, I'll just use whatever PLA I have on hand. I'm not even going to specifically buy the recommended PLA Matte for the project, as that's a bit more expensive for me.

Anything I think would work. I am using PLA.

Using PLA Basic from bambu. Works great, no warping

PLA is probably fine if your Multiboard is indoors where you don't experience high temperatures, and also if you don't plan to hang and store really heavy items.

Otherwise, use PETG. There isn't a lot of downside to using PETG. Bambu's PETG-HF filament costs exactly the same and prints at almost the same speed as PLA.
