Compacter

Compacter is a mod created by bdew. It adds a single machine of the same name, which allows for the automation of 2x2 and 3x3 single-item crafting recipes. For example, Redstone can be provided with the 3x3 setting to produce Redstone Blocks.

The Compacter machines can run on Energy Units, Redstone Flux, Forge Energy, and Tesla, so in order for the mod to be properly utilized it must be accompanied by a mod that allows for the production of any of those energies.
