Yes, I know, I'm just as bad as the box stores as I am already designing, printing and publishing Christmas things even before Halloween.
A Mini Merry Marblevator Christmas Tree is a smaller version of this thing "http://www.thingiverse.com/thing:598343". Only four parts to print ("Track.stl", "Auger.stl", "Cap.stl" and "Star.stl") for a functional "A Mini Merry Marblevator Christmas Tree", additional parts will be included soon if "ornaments" are desired.
Designed using Sketchup Make 2016, sliced with Cura, and printed on an Ultimaker 2 Extended.
