Power terminal shield

The power supplier used in the many of the 3D printers (type e.g. S-180) has very flimsy power terminal cover. The high power line terminals are just hair length away from the fingers or tools. The cover has not locking mechanism either. For the electric safety, I made the additional cover which keeps also the original cover locked.,

You might to add the heat ´shrinking tube to cover the power terminal connectors.
