I found this on Thingiverse, thought it'd be good to bring it over to Maker World as well since the other ones I found weren't quite what I was looking for. This one seems so simple and nice. Hope it helps! 

These are not my original files.

Here's the copied description:

Summary

This model of the iconic Seattle Space Needle stands 40 cm tall.

[7/20/2015] Update: Fixed the center screw and made the antenna thicker.

Instructions

This model prints without supports though you may want to use a raft for the tall slender pieces. You may need to glue the lower part of the top observation deck to the legs and the bottom part of the legs to the base. The rest of the pieces screw together so that they can be separated for transportation or replaced if broken.

For best results printing the antennae in Top1.stl set fan power to 100% and use a minimum layer duration of 5 seconds.
