I honestly think this is the worst use case for a 3d printer. The part isn't improved by printing. You can buy the part easily. The cost of modelling time and printing is more than the replacement. There's a decent chance the replacement part would have arrived quicker than the print took.... Sorry to be a bore, it's better than an octopus or another benchy, I'll give you that.

Oh, is this a poke at the Disney copyright expiring?

Nice

Uhh... Conspiracy theory confirmed?

For every self help group there are hundreds of forums for hate speech. For every open, sane discussion there are hundreds of discussions that are railroaded by trolls. I agree that a transparent state is brilliant, but the reason for transparency is accountability and the individual needs to have that accountability also.

So few people care about this that it's never going to stop. There are far more negatives to be solved by reducing anonymity than the positives of keeping a semblance of privacy.

China accounts for 30% of global emissions and, granted the states is half that, but they are still number 2. Also, the per capita number suggest that it would be easier for the individual to make a difference in the states.

Arguably a lot of China's emissions come from industry. As America has outsourced a lot of it's Industry to places like China these emission stats are probably somewhat warped.

You should have inverted his colours. Lol

A quick search for 2 channel 24v fan controller yealded the below link. Not saying this is ideal for your scenario but something similar will work and can be powered with a power brick. Doesn't look like it comes with instructions though so I'm not sure what current it requires. The temperature sensor could work to make it turn on when the printer heats up as well.

Because they didn't actually live in caves that often.

The image of these people living in caves arises from the fact that caves are where the preponderance of artifacts have been found from European Stone Age cultures. However, this most likely reflects the degree of preservation that caves provide over the millennia, rather than an indication of them being a typical form of shelter. Until the last glacial period, the great majority of humans did not live in caves, as nomadic hunter-gatherer tribes lived in a variety of temporary structures, such as tents[4] and wooden huts (e.g., at Ohalo). A few genuine cave dwellings did exist, however, such as at Mount Carmel in Israel.>

It's all relative, someone who never touched on Fourier or Laplace might see Pythagoras or trigonometry as the peak of mathematics and something very difficult. There will be some hardcore mathematicians that dream in Laplace...(shudders)
