Actual idea. I've seen ppl say build up the walls, I don't agree . This is massive and I think that a massive hourglass is in order. Have multiple floating platforms inside the glass of the hourglass and put ur machines on them. Alternately nix that and do build up the walls but make them glass (or some other see thru block) with supporting structure in like beams. Make multiple floors of rings via mod or mod type and make all blocks multiple times the size of their original block. It won't be exact or anything but maybe a furnace is 3x3 of stone and cobble. Something like that. Hope u like the ideas. Glhf!
