Immersive Engineering's unassembled multiblocks, saved in Create's schematic format. Once this is installed, you can write them to schematics and "print" them in the Schematicannon.
To install, unzip to your Minecraft installation.
Developed for 1.19.2 but in theory should work in all versions as long as the relevant block IDs and blockstates haven't changed.
