Leaf LED string

You can make the led string, however long you like and with as many leaves as you want.What you need: Some wire2 stranded cableSome yellow and red LEDsSome 50Ω resistorsBattery holder for 2 AA or AAA batteries3d printed leavesHeat shrink tubing or electrical tapePrinting:There are three different leaves which all can be printed on their flat base without support. You should print it with translucent filament, often sold under the color natural. I printed it with perimeters only.How to put it together:The Electronics are very simple:You have your batteries outputting three volts with a switch. There are three LEDs per light. These are soldered together in parallel with a 50Ω resistor in front. All the led groups are soldered in parallel. Assembly:Soldering the LEDs: This can be quite tricky, but I'll show you the way I found works the best.First lay out the resistor and a piece of bare wire in front of you like shown in the image.Lay the LED on the wire and the resistor and solder it to
