Robotic Flexi Cactus Design

I’d like a playful, interactive cactus that mounts on a small vase and behaves almost like a tiny robot. When I trigger it with a micro:bit the body should sway side-to-side and then spin a full 180°. The stem must remain visibly “soft”, so please design it with flexible joints or a TPU sleeve while still leaving firm pockets for the hardware. Electronics I already have on hand • micro:bit + matching extension board • two micro servo motors for the wiggle and the rotation • an ultrasonic sensor for proximity detection • several RGB LED beads to make the pot glow Your model needs to include precise seats and cable channels for all of the above, plus screw-posts or clips so I can open the shell, swap parts and run wires without tearing anything. The vase should hide the batteries and extension board while keeping the micro:bit’s display visible through a small window. Deliverables • 3D CAD files (STL and source) ready for FDM printing; flexible parts called out separately for TPU • an exploded view or simple assembly guide showing where every board, servo, LED and sensor sits • a wiring diagram that matches the micro:bit extension board pin-out • short test code (MicroPython or MakeCode) proving the wiggle, rotation and LED reaction to the ultrasonic sensor I’ll print and assemble here, so clear tolerances and step-by-step photos or renderings will be the key to acceptance. Feel free to recommend tweaks for balance, servo placement or weight distribution—everything has to move smoothly without toppling the vase.
