Servo Flower

thingiverse

This lamp was inspired by the majestic Lotus flower. Twelve individual leaves comprise its structure, each equipped with an SG90 servo that enables movement. These servos are controlled by a dedicated Arduino Uno system. Initially, I aimed to control the servos using a light-sensitive resistor, but for assembly purposes, a potentiometer was used instead. To facilitate easier assembly, I created a simple Arduino sketch. This sketch utilizes one potentiometer to control all twelve leaves. If you're unsure about installing the servos and potentiometers (light sensors), consult the official Arduino website at https://www.arduino.cc/en/Tutorial/Knob for guidance. I divided the servos into six pairs within this sketch, as depicted in the accompanying picture. The Leaves and LED holder were printed using a "spiral vase mode" technique. Each pair of leaves was printed as a single unit, requiring subsequent cutting with scissors. Most leaves were printed using a 0.4 mm nozzle, resulting in manageable cutting processes. However, printing the orange large leaves with a 0.5mm nozzle proved more challenging to cut through. To simplify the cutting process, I recommend limiting the base (bottom) layer to one or two layers. After printing the leaves, I glued them onto their respective holders. The LED holder was also printed using "spiral vase mode." To install the LEDs, small holes were drilled at the top for wire access, and two slots were cut out at the bottom for passing through servo wires. The utilized LEDs are 1w units that require attachment to a heat sink. I created custom heat sinks from aluminum pieces in flower-inspired designs. For guidance on driving these LEDs, consult another model available at https://www.thingiverse.com/thing:2662544. The base of the lamp was printed using traditional methods, necessitating support material. When attaching the leaves' arms to their servos, the included screws can be used for mounting. In my case, I chose not to use a screw. The "servo test fit piece" provided allows for testing the mounting hole's compatibility with the leave arms/holders. To complete the assembly, you'll need four M3x10 bolts and four nuts. The servos are designed to be installed without screws, allowing for easy interchangeability like Legos. For securing the bottom lid, small wood screws (or those included with the SG90 servos) can be used. A simple video demonstration shows the lamp being opened and closed using a potentiometer: https://www.facebook.com/100000611642601/videos/1739710949392610/?id=100000611642601. This model was printed in PET-G material. The included file "fully ass servo flower.zip" serves as a fully assembled example of the model.
