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.
Nice
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)
Well, it’s kind of obvious. They’ve had lots of close wins and a few blowout losses. Maybe it’s a tactic, if you go down by a couple, give up and save energy for the next one haha.
