Step 9: Track piece #6
1-2: Build this part. Note that the blue rod on the track connector is on the side slot, not the middle one.
3-5: Make this track part.
6-7: Put the two together.
8-9: Make this panel.
10-12: Make this part. Do yourself a favor and pay tons of attention to the 3d connectors.
13-14: Attach the two panel-ish pieces.
15-17: Build this longer track piece.
18-19: Snap that long track bit onto the top of the frame you just made.
20-21: add that weird piece you made first onto the end like so. If you made it properly, it should droop sadly.
22-24: Connect it all up to the main lift/track piece.
Yay! We have track on the left of the lift too now.
