This is a squonker that gets me thru the day without changing batteries or refilling. There are many readily available mechanical squonk mods, and quite a few regulated ones, but all that were not vaporware (hah!) only had a single battery and/or tiny bottles. So I designed my own, and it worked so well that I've been using the beta version exclusively for half a year. The chip/electronics are taken from an Eleaf Aster mod, as that's the cheapest I could find which supported the great ArcticFox firmware. Accordingly, this is a 75W device, but when printing it from PLA you should probably not run it at 75W for too long or it may soften. At around 30W, heat is not an issue.
