Quadcopter True X Frame Base

Create a 3D frame model for an FPV quadcopter in STL and STEP formats. Frame Type: True X. Size: 4 inches. Printing material: ABS. Purpose: lightweight FPV drone with such components: - motors 1504, KV 2000-2800; - 4 inch propellers; - F405 flight stack measuring 30.5×30.5 mm; - FPV camera 19 mm. Design requirements: 1. The central platform: - stack holes 30.5×30.5 mm; - additionally make holes for 20×20 mm and 16×16 mm for compatibility; - provide space for ESC/VTX and wiring. 2. Motor mounts: - 4 identical fasteners; - True X location; - triangular motor mounting; - the distance between the holes is 10 mm; - hole thread M1.7; - strengthen the attachment areas of the motors. 3. Geometry: - size for 4-inch propellers; - the center-to-center distance is approximately 160-170 mm; - 5-6 mm thick beams for ABS; - the central part is 3 mm thick; - smooth enhanced transitions from the rays to the center; - remove sharp corners, add rounded edges for durability. 4. Additional information: - mounting the battery from above under the 20 mm belt; - tie holes for motor wires; - 19mm FPV camera mount with 25-30 degree tilt angle; - place under the receiver; - protective sides around the camera. 5. Optimization: - the model must be designed specifically for ABS FDM printing; - avoid long thin elements; - make the structure as light as possible, but rigid. Output files: - STL ready for printing; - STEP parametric model for editing in Fusion 360 / FreeCAD. Before creating the model, make sure that all the holes have real dimensions for the specified screws.
