I needed a light for my Creality Ender 3 printer so I can capture better videos with my camera. This design can be used to other printers that have an aluminum profile extruded bar at the upper side.
I used 2 pieces of this LED Rigid Strip Tube Bar Light Lamp With U Aluminium Shell and PC Cover (https://www.banggood.com/50CM-SMD-5730-36-LED-Rigid-Strip-Tube-Bar-Light-Lamp-With-U-Aluminium-Shell-PC-Cover-DC12V-p-1088115.html?rmmds=myorder&ID=233520867&cur_warehouse=CN) which I cut it in a suitable length.
In order to mount it on the aluminium profile I used M5 T Sliding Nut Zinc Plated Carbon Steel for 2020 Aluminum Profile (https://www.banggood.com/50pcs-M5-T-Sliding-Nut-Zin-Plated-Carbon-Steel-T-Sliding-Nut-for-2020-Aluminum-Profile-p-1048439.html?rmmds=myorder&cur_warehouse=CN) and M5 screw.
Also, I used a rocker Switch (https://www.banggood.com/5pcs-Black-Push-Button-Mini-Switch-6A-10A-110V-250V-KCD1-101-2Pin-Snap-in-OnOff-Rocker-Switch-p-1096122.html?rmmds=myorder&cur_warehouse=CN) to power ON/OFF the lights.
For power supply I currently used a workbench power supply but I am going to use a step down power supply module (buck converter) to power the LED strips directly from the printers power supply. The total power consumption is about 8,5 watts @ 12 volts (0,7 amps).
The left part has support brackets for mounting the cables but the cables I finally used couldn't fit and I used a blade to remove them. It's ease to remove them so I did not removed them from the design in case someone find them useful.
The distance between the LED strips and the printers mechanical parts is considered during the designed and tested with the final product so it can not interfere with it.
