Mounting brackets for a 10x30mm plastic drag chain, to contain the Sprite Pro extruder's ribbon cable. Replaces Sprite Pro cable holder and Ender 3 X-axis belt sprocket cover. Uses M3 hardware to mount chain, but you can probably use the Phillips screws that come with the chain. Also contains a standard picatinny mount for attaching cameras/lights. T Slot mounting nuts are required to mount the Z axis chain connector to the base.
