This is my 7th KNEX ball machine "Mutualism." This took a little over a month to build with 2 lifts and 5 paths, here are more details.
HERE'S THE VIDEO if you haven't seen this yet:
Step 1: The Bottom & Network
This is where the balls land when they reach the bottom. Then, the balls go up one by one by mathsboy314's Multiple Arm Lift and a Chain Lift.
Step 2: Path 1 (path 4 Connects)
The beginning of this path is the same as the path 5 start out. This path features 95martb's halfpipe element & one of Kairah89's elements from Metropolis.
Step 3: Path 2
This path connects to Path 1.
Step 4: Path 3
This path features Kairah89's spinning basket that doesn't always work for me.
Step 5: Path 5
The two things featured on this path are the panel stairs and panel drop both by 122Heb (Knextreme).
