I made this LED stand that works perfectly for the cr-10 but it should work with anyone printer that has a aluminium extrusion, such as a tevo tarantula. The stand is adjustable along the extrusion so you can move it to avoid other mods such as a webcam mount as show in the picture. Here's the parts you'll need to make this work.

Wires, you may already have some: http://amzn.to/2hPPudz
solder and soldering iron.
Start by attaching the LED strip to the top part of the print. Then solder the wires to the strip. Guide the wires to the second strip or directly to the power supply. Make sure to find out if your power supply is 12v. Cr-10 and tevo tarantula's are 12v.
