MQD-120

The 120mm quadcopter model was designed for the Frustum challenge, addressing needs such as topology optimization, efficient airflow and heat dissipation, mounting spaces for electronics and payload, and 3D printability with minimal overhangs. With a weight of 18-25 grams depending on material and fill rate, it was made using PLA and PET in simulations. Successfully printed on a Voxel8 3D printer, it underwent two iterations through the Frustum "Generate" platform for valuable feedback on geometry and thickness. Changes were manually added to the SolidWorks file for symmetry and editable design. Velcro straps, tape locations, and rubber band slots were integrated for retention. The design supports 2.5-inch tri-blade propellers, has angled openings for increased airflow over components, and ensures proper center of mass and symmetry via SolidWorks tools. Build time is approximately 120 minutes at a 60% fill rate using PLA. Additionally, the modular design allows for conductive traces to be added by conductive 3D printers like Voxel8 for embedded connections if desired.
