Intro: 3D Head Lamp
You will need:
LED Strip 4"
Step 1: Laser Cut
Begin by laser cutting your pieces.
We're using the FSL Hobby Laser.
The "Base" file includes two parts. This will make the solid and the hollow pieces to stack. Cut along the red lines and engrave on the blue line. Only one piece requires the blue line to be engraved.
Using 1/8" material, cut the file 8 times. This should leave you with 8 solid pieces and 8 hollow pieces. Save one of the centers of a "Hollow" piece. This will close the base and be our guide for placing the LEDs.
For the acrylic, engrave the black sections. Cut along the red line.
Step 2: Glue
Stack the slotted pieces to make a solid piece. The slots will be a tight fit for the acrylic. Use the acrylic to make sure that all the slots are aligned as you're gluing. If you plan on making the lamp interchangeable, be careful not to glue the acrylic into place.
Once all the solid pieces are in place, begin gluing the disks to make a hollow cylinder. Glue this cylinder underneath the slotted pieces. This will give you the space for your electronics.
Step 3: Wiring
Create a circuit following the attached diagram. We used a 9v battery, and two sections of a 12v led strip. Other combinations are possible, though some circuit math may be required.
Adhere your LED strip to one of the excess pieces from the "hollow" circles. Align it to the engraved rectangle to line up with the base of the acrylic. Secure all the battery and the wires to the base. If you have a switch, you can drill a section of the base to set the switch for access from the outside.
Step 4: Finishing
Sand along the base to get a smooth consistent finish. Add lacquer or paint as desired.
Place the acrylic in the stand. Add the bottom circle with the electronics to the base.
