It said that I was missing unknown parts while trying to place it, but let me build it anyway anyway. Gave it a shot and sent some stuff through: and sure enough, out came heat sinks. Took a peek inside and was met with the dark horrors of a different dimension, so I've backed off and let it tug along in peace. Works as intended, 5 stars!

Not sure why this was rated one star. It may be non-euclidian staring into Cthulhu dreaming on the inside, but ingredients go in and heat sinks come out and it is the only factory that does that I found in blueprints, and it does it perfectly. I'd prolly rate it 4 stars normally, but I gave it 5 to balance that bizarre one star. :P
