Here is my design for a couple of light bars I bought from AliEpxress a while back
Light Bars - AliExpress Light Bars. I have the 20 cm ones
I printed mine in White Overture PLA Pro. I designed it so there is no need for supports, just a brim on the wire clamps.
You need to print one of each of the brackets and the wire mount. You will need at least 8 of the wire clamps.
You will also need a couple of M3x10 bolts to screw the mount into the existing holes in the frame just above the controller board.
For the buttons, you can either rewire it like I did to move the button up the cable or you can just wrap it up with a zip tie.
