(re-uploaded from Thingiverse, Space Needle Model is by Intentional3D, Lamp holder is by me)

This model of the iconic Seattle Space Needle stands 40 cm tall.  (44.8cm if size is increased to 112%)

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.

(I found increasing the size on all parts to 112% gives better results)

(included lamp holder is already sized for 112%)
