The Tunnel is a device added by Compact Machines. It is used on the inside of a Compact Machine that functions as a multi-purpose pipe typically used for transferring items and Redstone Flux and its variants using Forge Capabilities between an outside block connected to the Compact Machine and a block that is placed adjacent to the Compact Machine Wall onto which it has been placed. When installed on a wall, the Tunnel will show as a variation with a square corresponding to the outside face it is connected to being highlighted a different color. Right-clicking the block will cycle between the faces to which it may attach, or will disconnect and return it if the end of the options is reached. Unlike the Redstone Tunnel, the direction of the established connection depends entirely on the connected blocks.
The Miniaturization Field Projectors must be set up with a minimum build area of size 3 to complete the crafting.
