The prompt
Design a fully 3D-printable *X-frame brushed micro quadcopter* in PETG. *Goal:* printed frame/body INCLUDING prop guards ≤20 g, target 5–10 g. Use a 0.4 mm nozzle and minimize material while maintaining stiffness. *Motors:* 4× 8.5×20 mm brushed coreless, ~50,000 RPM. Create 4 adjustable motor mounts and 4 thin integrated circular prop guards. Make motor spacing, prop diameter and guard clearance editable. *Electronics:* ESP32-S3, MPU6050, TPS63031 buck-boost, 2× GY-530 VL53L0X, 2× DRV8833, 1S 540–550 mAh 50C LiPo. Create a lightweight open center skeleton, not a solid plate. Use ~1.5 mm main structure, up to 2 mm around motor mounts, and 1–1.2 mm guards. Use thin arms, triangular reinforcement and rounded transitions. *Mounts:* Create separate adjustable slots/holders for every component. Keep MPU6050 rigid and centered. Keep ESP32 accessible with both USB ports exposed. Mount TPS63031 near ESP32. Mount both DRV8833 near the center. Mount one VL53L0X facing forward and one downward, both with unobstructed views. Add an adjustable LiPo tray with retention slot/tabs. Use 0.3–0.5 mm clearance around boards. *Wiring:* Add lightweight cable holes/channels and small retention tabs for motor, battery, I2C and control wires. Keep wires away from propellers. Keep all dimensions and mounting positions parametric/editable. Do not guess unknown board, battery or prop dimensions. Add tiny landing feet only if weight allows. Optimize for low weight, stiffness, low vibration, centered CG and easy assembly. If estimated frame weight exceeds 20 g, remove material and optimize. Export editable CAD plus STL and STEP if supported.
