Hi! Forgive my ignorance, but how would this improve the Lulzbot Hex Head? Heat retention? Keeping the nozzle clean?

Both of these are the intended effect. A lot of printers come with cotton batting wrapped in kapton tape to achieve a similar effect, but that tends to degrade quickly and requires disassembling the hotend to replace. These are able to be slipped on and off at will, and cover the hotend all the way to the tip of the nozzle to prevent filament from sticking to, and building up on it. They also insulate the block for better heat retention.

They're not perfect, as RTV silicone will break down over time, but they're a vast improvement over cotton+kapton or nothing
