Anet A3 Power input cover

thingiverse

The underside of the Printer is exposed to the world with high voltage connections visible on the input mains connector. This cover transforms the unit from IP 0 to at least IP 1. Another cover is currently in development to conceal the other end of the high voltage cables into the PSU and will be available separately. A 3mm screw hole must be drilled and tapped or modified to accommodate this cover, which secures it to the connector with a screw. A second 3mm screw and nut are used to fasten the unit to the underside of the base. On my unit, I discovered an existing hole that I utilized. You might need to cut the cable tie holding cables in that area, as on my unit, those requiring coverage were obstructed by other cables secured by the cable tie. The cover on my unit reroutes the cables coming through a corner hole and high voltage wires from the connector, which all exit through a flexible door. This design meets the finger protection requirements for IP ratings and provides peace of mind that my grandchildren will not be electrocuted by high voltage shock. The UK 240v standard applies.
