3D Printed Oil Derrick (x5)

An oil derrick is a drilling rig designed for use in oil and natural gas production. The basic version has an upright stationary section which is potentially capable of supporting hundreds of tons of weight, combined with a movable boom which is used to raise and lower equipment. Derricks of various designs have been in use for centuries to extract valuable resources from under the Earth, and continue to be widely used today.
