Linear Extrusion Tower

What is a castle without magnificient towers on all sides?

This will generate the towers for my castle.
Made with OpenSCAD while learning how to program with OpenSCAD.

• I wanted the tower to have stairs on the outside.

• I wanted it to be generated with linear_extrude, playing around with the number of fragments and the twisting angle.

I love Symmetry! See how beautiful it looks from above?

Later I will upload the whole castle.
