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

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.

I have 4 of these. Two of them are the ones that have integrated water catchers and only overflow if they are overwatered. One I’ve put a saucer in with the pot and one I just have to put a towel under it. I’d say the best option is the one with a saucer, you can visibly see that it’s flowed through, you can add gravel to improve humidity.

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.

I disagree that the main reason is thermal runaway. It is more likely to be underrated components that can’t handle the current. This would not be immediately apparent and does usually come from lower quality printers.

The other comments have this covered but bare in mind that if you’re in the northern hemisphere we are heading in to the dormant season and it will require even less water.

I think it’s the PH part from some other comments but I can confidently say the moisture part works pretty well. I have been using one for about a year and it’s been helpful.

Anyone know off hand if liquid seaweed covers all these bases?

It gets a mist a couple of times a week and is watered regularly, it gets fed with liquid seaweed around once a month. Our house tends to stay between 40 and 60% humidity which probably helps. It can get a few crispy ends in the winter but then I try and mist it a bit more. Funnily enough we bought two at the same time and the other one didn’t last long, this guy is a strong one.

My wife and I bought a couple during lockdown and things have grown from there if you’ll excuse the pun. We’d only just bought our first place together and it was our first opportunity to own any. We now probably have a few too many!
