This is an adjustable LED lamp that is large enough to accommodate two sections of a 5050 LED strip that measure 10mm x 50mm each (totaling 10mm x 100mm together). This is six LEDs.

Hardware: You will need two to three 12mm long M3 screws, and two to three 2.2mm thick M3 nuts (depending on the number of points of articulation you choose). I used cheese head screws. The mount attaches to the printer with the screw that came with the printer.

LED Arm Options: There are two of these that you can choose to print from. Light-LED_Arm.stl requires you to print Light-Angle_Connector.stl to attach to the connector arm, and gives you an extra point of articulation. If you decide that you don't need this extra movement, you can simply print Light-LED_Arm-With_Angle_Connector.stl.

Connector Arm Options: There are two of these that you can choose to print from: a honeycomb pattern or a triangle pattern.

Knobs: Print the knobs separately from all other parts. You will need to pause the print part way through so that you can insert M3 nuts, and then continue the print.

Check out the enclosure I created for the Monoprice Select Mini that lets you bring in a second power source and install switches to turn LEDs and/or fans on and off.

UPDATE: I have uploaded the file "Light Arm 2" which has added structure to the arm to support the weight of the LEDs over time, and also includes a channel for running wires.
