Maximum Compact Machine: 13x13x13 room.The blocks are small rooms, when you right click them with the tool, you transport inside the room. The core item in the mod is the Personal Shrinking Device, serving as the mod manual and the primary tool, as right-clicking a compact machine block will transport you inside it. To actually shrink something, you need 10.000 FE (Forge Energy) and 1000mb (milli buckets) Shrink-Pym-Particles.
Mods are both in the description.Make sure you subscribe and hit the bell.
Compact Machines is a mod introduced to FTB in the direwolf20 1.12 modpack, which allows you to create complex machines in one block. You can either use the Stirling Generator from ThreeCore and put it next to it, or you use one of the many energy mods that support Forges energy system. I show off two mods that work together to put you to the size of a minecraft pixel.
