Z Axis bar wire guide With optional LED LIGHT RAIL.. Take the wires off your Bowden tube. For CR10, Ender2&3,Tornado,Michelangelo and U10

Added a little better inderect lighting bar for the Ender3, Cr10 and Tornado. You use 2 rows af light under the mount and the front wall directs the light towards the print.
Here it is on my Ender3.

Added U10 LED Bar and some pics of the indirect light bar. The indirect puts out a lot of soft light.

Added an indirect light/ light bar. It will probably need to be printed in white for best reflection. You mount your LED's to the back inside portion of the bracket that mounts to your rail and let the light bounce off of the angled diffuser. Will prototype when my whit filament gets here. Try it if you like.

Added LED light bars that can be added to the existing X axis wire bracket to install LED's just below the Z rail. Those additions will fit the Tevo Michelngelo and the Creality Ender 2

TEVO has extra 5mm T-Nuts, CR 10 has extra 4mm T-Nuts, I liked the 3mm T-Nuts.
No matter what T-Nuts you want to use there is a Z Hanger and LED Strip for you. Just mix and match the parts you want to use based on your T-nuts.
