I was in need of a simple light to put underneath my desk to light up my 3D printer area. I knew I was going to have access to an AC outlet plug so for this build I used a small AC to DC 15 Volt power supply, but this can also use a 9Volt battery to power the light module and then can be used anywhere. Light up a tree house, a fort, or while camping in a tent!

3D Printer
Clear PLA for the lens and PLA for the case (Whatever color you want the case to be)
A small 12 to 15 Volt power supply or a 9Volt battery with battery clips
Optional: Power switch
Hot glue gun
Heat gun
Scissors
Oven mitts
Soldering iron
Small LED board (The one I am using is 9 to 12 volt DC) similar to these : https://www.goldmine-elec-products.com/prodinfo.asp?number=G20004
Milk jug (a strip of an opaque milk jug container can be used to make the diffusing lens as well)
Print the Case and Lens

Print the Case and the Lens on a 3D printer. If you don't like the size or shape you can start with these files and make modifications.
You can get the Tinkercad files here for the case:

Assemble the Lens and Case Top

I cut a large section of a milk jug and used the lens mold to make the opaque lens. I used a heat gun to heat up the plastic strip just enough. Wearing oven mitts to protect my hands, I was able to firmly push the plastic around the mold. Trimming the lens to size and doing a fit check the lens was done.
Using hot glue I assembled the diffusing lens and the top of the case.
Place the LED Board

Solder your power connection, the switch (if you are wanting a switch) and the LED board. Be mindful of the polarity of the power supply (Battery) and the LED board.
I used hot glue to mount the LED Board into the case, making sure to center the board in the lens area.
Verify it works and is located in the location you want the LEDs to shine through before moving on to the next step.
Place the Bottom of the Case

I put a few drops of the hot glue around the case bottom and placed the bottom into the top and allowed the hot glue to hold the case together.
Mount Your New LED Light

Having this little light is really great to light up my 3D Printer work area and provides plenty of light when i need to change PLA or remove a project from the printer area.
