Hi Al, here’s the link to the file:

This is an assembly with all parts needed, including the brass rods and a bit of thread+brass rings to lift the main chute.
You’ll have to separate the parts for printing yourself, sorry bout that.
The counterweight, guide rods, main liftable chute,associated pulleys and yoke, are all optional. That was the fashion for mines in my my area of interest, but feel free to not print those and instead lengthen somehow the short fixed portion of chute. Just watch your clearances with your trains!
