Snowflake circuit holder

The permanent support structure holds down the most warping points, corners and long straight edges. To prevent the branches from becomming just another source of warped corners when hot layers attach to cold layers, their thickness increase gradually from the tips that don't have many hot layers cooling and shrinking on top of them. I needed something to prevent a small circuit boards from flipping over by the combined tensile strength of connected cables. The branches allow taping or binding the board to a surface. An anti-static sheet can be taped on the back to make it safer. I used my board with 4x4 white LEDs and a 2-pin 12 volt MTA100 power port to illuminate my printing chamber with the same power supply that drives the ventilation for the active coal filter. By having four leds in serial for each lane, each LED is given 3 volts, because 12 / 4 = 3. Blue, green and white LEDs can usually handle 3 volts because a shorter wavelength needs more energy per visible amplitude. Red and yellow LEDs require lanes of 5 in serial to get 2.4 volts in each.
