Inspired by https://www.reddit.com/r/CreateMod/comments/11qhx88/i_heard_we_are_discussing_horrible_unpractical/
I decided to take inspiration from it with how it uses dropped items & fans to move them so I made it practical
Put whatever you need on top of the 3 top-facing fans, like lava for smelting, you know
Any block (unless you use lava, then it needs to be fireproof) can be used as a replacement for the trapdoors (You don't need the trapdoors/replacements if you use campfires/soul campfires/waterlogged leaves/modded alternatives)
The copycat panels must be kept empty, with leaves or copper grates
(i have no idea how to write descriptions)
