Ferris wheel, based on the N Scale Pacific Wheel by jeff_j3ffr3y (https://www.thingiverse.com/thing:3944620). I recreated it so it could be printed and assembled quite easily.
I included two base and support units, the first one is a simple one, the second one has a fence and a small slope for people to get into the gondolas. The gondolas should fit nicely between the slopes.
Before assembling, make sure all the gondolas can turn freely around their axis. Also check that the two wheels fit together, in case one of the pins is a bit thicker than expected.
