Crystals (halogens) LED lamp

Hello everyone, I recently stumbled upon some beautiful LED lamps online at https://www.thingiverse.com/thing:3285975 or https://www.thingiverse.com/thing:3234211. I was inspired to create something similar but with a crystal-like appearance. After designing and printing one, I'm excited to share my experience with you. In my case, I built it for a single star power LED (1W blue, 350mA, 3.4V) without a radiator and powered by a micro USB socket connected to a smartphone charger (5V, > 1A). The circuit is straightforward, requiring only a 4.7 Ohm/1W resistor. Here are the parts I used: * Star power LED: https://botland.com.pl/en/leds/2494-power-led-star-1-w-led-blue-with-heatsink.html * Micro USB socket: https://botland.com.pl/en/accessories-for-breadboards/7668-5pin-microusb-to-dip-adapter.html?search_query=micro+usb+socket&results=859 * Resistor 4.7Ohm/1W Important safety note: Be cautious when connecting a smaller resistor, as the LED may heat up and burn. Always verify that the resistor meets the required parameters - it can have more resistance but never less. Remember that every diode's power consumption depends exponentially on voltage, so small changes will cause significant increases in power consumption and heat emission. The upper part of this design requires supports, and printing time exceeds 8 hours (at 0.2 mm and 100% speed), so be patient!
