I saw this on Twitter earlier and the photo somehow gave the slightest sense [1] that the laptop was flexing under some strain. So I wonder, even if that's not the case here... :-) how much would it take, and what would happen? Would the cupholder break first or would a key cap fly off first? And what is on the top-10 list of the least-safe 3D-printed laptop accessories? 1. https://twitter.com/FrameworkPuter/status/1653103668730949632/photo/1 https://twitter.com/FrameworkPuter/status/165310366873094963...

In the shared design and printed out of normal filaments, the cup holder will break long before anything happens to the laptop. The cup holder was tilting slightly because the rails on that printed part need to be tuned a bit to be tighter. I think the design was based on our shared reference design, which we deliberately made slightly loose for printability (under the mistaken assumption that nobody would build something load-bearing using it).

I can see it with PLA, but i thought PETG was supposed to handle it fine (as long as you are not using it with giant glasses filled with liquid). And PETG is pretty much the second most common type of a filament after PLA. Note: i could be entirely wrong about this, but I was under the impression that this use-case is exactly what PETG is made to handle.

  Out of curiosity, could the expansion card slot bear the entire weight of the laptop if it were used to hold the laptop aloft?

    Probably, the laptop is not that heavy and there is a good few square centimeters in the slot. If you are have proper support (aluminium or steel) then it should easily hold up the weight. That said, I wouldn't lean or even type on the laptop if it was suspended over an empty space like that. I don't think there would be much resistance to the laptop sliding off the support sideways either.

looks like lens distortion or similar to me
