Anet A3 PSU Safety Cover

thingiverse

Having thoroughly examined the Anet A3's design, it was clear to me that electrical safety had been given scant consideration. A separate design for the input connector is a must, and this design is an important addition, albeit not as crucial. It's a straightforward box that covers high-power connections, thereby preventing fingers from accidentally touching them. After printing the box, two holes need to be drilled and tapped on the side, then secured with two 3mm screws. I've provided pilot holes to make this process easier. Alternatively, you can modify the design and print screw threads if preferred; however, I found it more precise to tap by hand. Please let me know if there are any improvements that can be made to the design. Currently, I'm working on earth bonding due to recurring shocks from metal work, which could potentially be caused by static electricity – a problem that also needs to be addressed.
