This is a custom frame to turn an old desk lamp into a magnifying lamp, with just a lens and some LEDs. Note, that the mount IS NOT universal. However, the .dwg file has been included so that other mounting solutions can be designed easily.

Materials and methods

- No supports, 15% infill
- Everything should already be oriented correctly, but make sure the LED holes are on the top.

- 100mm diameter magnifying lens
- 12 3mm LEDs (and the resistors, wire, and power source to power everything safely. I used four parallel rows of three white LEDs with a 120 ohm resistor on each row, and a 12 volt wall wart.)
- 1 meter(ish) of 3mm diameter insulated cable with at least two conductors (old USB cables work great for this)
- 4 M3 screws, between 11 and 6mm long
- 4 3mm washers (optional)
- Articulating desk lamp arm with the correct mount. Basically, I had an old lamp laying around that I built this for. However, I've included the .dwg files so that other mounts can be designed.

- Wire up the LEDs, using the printed holes as spacers during the soldering.
- Attach the insulated cable to the positive and negative ends of the LED array, then feed it through the extra hole between the twelve o'clock and one o'clock holes.
- Push the LEDs through their respective holes so that they fit snugly.
- Slide the lens in from the bottom, until it's situated inside the bottom ring.
- Attach the lens_clamps to their respective slots with the M3 screws.
- Wire the insulated cable to your power supply, and you should be finished!
