Snowflake circuit holder

The main support structure keeps the most extreme warping points, corners, and long straight edges firmly in place. To prevent branches from becoming yet another source of warped corners when hot layers bond with cold layers, their thickness increases gradually from the tips that don't have many hot layers cooling and shrinking on top of them. I needed something to stop small circuit boards from flipping over due to the combined tensile strength of connected cables. The branches allow for taping or binding the board to a surface securely. An anti-static sheet can be taped onto the back to make it even safer. I used my board with 4x4 white LEDs and a 2-pin 12 volt MTA100 power port to illuminate my printing chamber using the same power supply that drives the ventilation for the active coal filter. By connecting four LEDs in series for each lane, each LED receives 3 volts because 12 divided by 4 equals 3. Blue, green, and white LEDs can typically handle 3 volts because a shorter wavelength requires more energy per visible amplitude. Red and yellow LEDs require lanes of 5 in series to get 2.4 volts in each.
