mechanical butterfly 3d model

Create a highly detailed 3D-printable mechanical butterfly body/chassis based on the reference image. Design a lightweight bionic butterfly frame with a symmetrical left-right structure. The main body must have a central compartment for mounting a small micro servo, with proper screw holes and a secure servo holder. Add two strong wing hinge/pivot mounts at the upper left and upper right sides. Add mechanical linkage mounting points for connecting rods between the servo horn and both wings. Include a rear/center compartment for a small LiPo battery and receiver/controller board. Add M2 screw holes, rod mounting holes, reinforced joints, and clean rounded edges suitable for FDM 3D printing. The body should be one practical mechanical chassis with separate removable parts where necessary. Keep the structure lightweight but strong, with thin reinforced arms and open spaces to reduce weight. No decorative details, no organic insect body, no realistic butterfly textures, no unnecessary
