Steel Spring

A steel spring used to create bouncing inventions.

Notes

A Steel Spring is a manufactured component used in advanced vehicles and furniture, including the Excavator, Scorpion, Skid Steer, Truck, and upholstered beds and sofas. It weighs 2 kg and stacks up to 100 in inventory. Since it is required for several mid- to late-game builds, keeping a stock of springs available in a public store helps ensure others can complete their projects without delays.
