I am not too familiar with Cura, but I don't think they have the 'support painting' feature of prusaslicer and the likes that would allow this. In those, you can paint where you'd like your support to touch or use modifier meshes to selectively add regions that should be supported. It's the easiest way I know, though I have heard that Meshmixer also used to be able to do that.. but I've never tried.
Check if your print is wobbling when it reaches that height. If it does, you may need to add support to fix that - a few organic support touch points halfway up should help
For me, it's mostly been about community - I got into bouldering because I met a few people who liked it, got invited to their WhatsApp group, and have been hanging out with them in and outside of the gym for the past year. We all have bad days, weeks, setbacks, and such, but we're supporting eachother and motivating one another through them.
In my experience, asking others for help with a bouldering problem, regardless of gym or (European) country, usually leads to at least having a buddy for at least the evening! I'd imagine taking a beginner course has a similar effect.
On top of some of the other tips, layer height being the most prominent, perhaps try a different soap or clean it with alcohol after. I've noticed a difference between soaps (and even between toilet paper brands) - some things leave a bit of residu I think.
There's no data on those, but we did at some point print air tight (0.8 bar over a week iirc, no vapour smoothing) in abs, so it may be similar. Consumer grade hardware of this sort is probably still pretty far away, but it's not as impossible as many believe :)a
I agree with all your points, except the last one. Admittedly, it is still rare, but there are companies out there that, using industrial machines, manage to get close to or (in case of the linked one) exceed injection moulding in tensile strength, and are achieving near isotropy using FDM processes. https://orion-am.com/blog/orion-am-news-1/3d-printing-peek-stronger-than-injection-molding-12

Saw it, loved it. All three are super skilled in both climbing and in being hilarious!
Interesting, thanks for the insight!
I'm not well versed in this at all, but would this also work if the "attacker" were to take a screenshot of the image they wanted to alter, and plug that into an AI tool? It sounds more like metadata tweaking from the article, which would be bypassed by a screenshot.
