Front LED turn signals for Huffy Cranbrook or 5 mm round

thingiverse

Clamps to the front of the frame on a 34-35 mm bike tube. Designed specifically for a Huffy Cranbrook. Tolerances are loose because I use a 1mm nozzle. I recommend printing the light base at a 45 degree angle with the tube on top and supports. The side of the clamp with the tubes should use support. Both parts of the clamp should be 100% infill. Requires 4 M3 x 12mm bolts and corresponding nylon lock nuts, 16 red LEDs, thin wire, 2 200 or 220 ohm resistors, and a 5 volt power supply. To trigger them, I use an Arduino Pro Mini (you need a special connector to program it, I suggest a Nano instead). I also use a 4 relay breakout board (though only 2 are needed) to supply the power and give the cool clicky noise blinkers make. My power supply is from a bike light, essentially it's just 4 18650 lithium batteries in series. That comes out to 8 or 9 volts, hence the need for a regulator. I haven't yet finished the project. I will upload the other parts and files as I make them. I have pictures but they're too big to upload. I will fix them later.
