I will second the drying filament statement. It’s genuinely shocking the difference it can make. Pretty much every metric is improved by using properly dried filament.

There are also food dehydrator mods out there on thingiverse/printables to convert a cylindrical dehydrator to work for filament without butchering the stands that come with it. Plus side is you can also make beef jerky with it :P

I think it’s funny that you think any country will have even 5% of their population actually come out and protest ANYTHING.

I did some googling and in the US, the 2017 women’s march was the largest march in US history with a whopping… 1.7% population participation.

And yes, there are some protests that had a big portion of their populations come out. Take 2019-2020 Hong Kong protests. Roughly 2 million people came out and protested, roughly over a quarter of the population. And you know what happened? Nothing. People were beaten, died, and China still got Hong Kong. And this was while there was still some local control of HK. Keep in mind, this is a people DEFENDING THEIR COUNTRY from an effective HOSTILE TAKEOVER and they got a quarter. A war taking .2%? Even if 1% were impacted, there’s no shot people are going to risk protesting when the world is doing that for them.

I don’t think the tolerances would be too bad. A lot of prints that have tight tolerances have a test piece that you print and test against a known object, which let’s you adjust your print to get tighter tolerances. Once you correct for the expansion of the plastic, getting the right tolerances should be totally doable.
