Combines 4 partially full Mk.6 belts of any item into 3 full Mk.6 belts without having to worry about the merging interrupting the flow and backing up the belts or machines. The leftovers are released on the 4th line. Untested with other belt speeds but should work with them as well (Just have to switch out the belts and lifts). Don't worry if the buffers fill up. That's suppose to happen and doesn't effect the merging. The blueprint comes with sign instructions on how to install it.

Enjoy the blueprint! - CovertRiot (Twitch/Youtube)
