The petals are not shown. The area under the trumpet has been bulked-up significantly to hide the sensor board.
2 of the images of semi-transparent so you can see the actuation mechanism and how the Teensy is positioned. The 6 wires from the main sensor board need to fold under that Teensy, or retract into the base, which is why I think the Teensy should be as flush mounted to the sensor board as possible.
10mm goosenecks with an 8mm entry is what ive managed to find, 6 ft with a half foot extra fabric bit. Here's the nozzle (8mm) and the body (10mm) am covering everything in gold fabric and this is the conical extension for the flower. I think you should use as thin wires as possible, threading it may be painful. We usually use a metal wire with the other electrcal wires taped to one end.
