12V LED Lighting

thingiverse

This 12V LED spotlight complements the LED strip lighting above my desk, providing extra illumination for reading or measuring tasks. To create this DIY lamp, you will need a 4W 12V MR16 light bulb, a rocker switch, a chocolate block terminal connector with 10mm x 4mm x 5mm metal inserts and an 8mm pitch, one 1A fuse holder, one 1A fuse, three M3x12mm screws, three M3 nuts, one M4x12mm screw, and M4 bolt. Additionally, you'll need wire, solder, and a 3D printer with replicatorG0040 software and the profiles supplied by whpthomas to print the necessary parts from Thingiverse (thing:39050). Follow these instructions to assemble your lamp, including extracting the metal inserts from the terminal connector, printing and inserting the MR16 connector, and attaching the bulb to the holder with clamps. For a tidy setup, you can also print a small switch box to attach to your monitor using double-sided tape. However, remember not to use mains voltage or 12V halogen bulbs, as they generate excessive heat and are unsuitable for this purpose.
