Car Unloading Replacement Structure for Tyco Trucking US1

This is a replacement structure for the Tyco Trucking US-1 "Car Unloader Action Accessory." The design is a little different from the originally, specifically in that it has a sign above the track where the truck enters. I added this to keep the plastic from flexing outward, which results in the trailer failing to unload.

You will need two copies of AutoDropoff_Part1, with one of the copies being a mirror image of the first. To connect the two sides, you will need 4 pegs made out of 1.75mm filament. I found it helpful to ream the holes with a 5/16 drill bit before inserting the filament "pegs"

The ramps are interchangeable with the original Tyco structure.

If you have problems with the mounting "lip" on the ramps braking off, you might want to try printing the ramps on their sides. It takes longer and uses a lot more support, but the mounting lip will be much stronger in this orientation.
