I redesigned nedallive's mount, as his would not fit my HEVO. It would interfere with the y-carriage. My y-carriage almost touches the top profile of the frame, mounting it under the top profile is not an option and when side-mounting it would still touch.
My mount sits central on the extrusion, with mounting screws on the side. I will fit normal led strip. Zipties can be used if needed. You might have to mirror the y-axis min endstop bracket if you want the mount to be centered front to back.
