This is a storage container that looks like an iconic tower from medieval times. Great for storage kids toys. The body is completely hollow and the top can twist on and off via custom threading. This was specifically designed to print on an Ultimaker 2+ Extended 3D printer. The model can be scaled down, but the outer walls may become too thin.
