I had three things that I wanted to accomplish to stabilize the bed connector, keep the wiring in order and support the Y axis frame.
I did lose some of the print area with the clamps, but that has not been a problem for me. I tie raped the wires at the bed end to make sure they do not move at the other end the wires are free. When using a drag chain the wires should be free at one end. The chain is mounted to the frame using the screws for the motor mount the stock screws were long enough. Then the mount is screw down to the base board.
The front of the frame is also mounted to the base board with a bracket that I have included. With the Y belt tighter in place there were two holes form the original Y belt idler that I used to mount the front bracket.
I wanted to keep things as simple as possible. The chain is close to the original RotoScan chain it has been around for a while.
I used this on my Anet a6 it may also work on the Anet a8
