(Not financial advice. I am not a lawyer.) If you're ever in a position where you're like, "geeze, I have this heater that like melts plastic and stuff, but I totally don't want to melt the rest of my self-printed toolhead" well look no further. Actually, you will need to look further because you'll need a cooling fan to go with this, but stop distracting me. What this product does is take all that heat coming from your plastic melty part and disperses it into the air, where it can be wasted. Which, if that sounds bad, it's not because the alternative is burning your house down when your printer melts itself to death. Now, sure, you may say, but aren't there cheaper heatsinks on the market? Well, yes there are, but this one specifically works with the version of nozzles that cost $50 each, for those of us with too much disposable income. And it has "Voron" in the name so you ^need^ it.
