Quadcopter hollow design

grabcad

Originally, I knew nothing about forces in CAD programs or generating quadcopter designs with brushless motors; I thought velcro straps would suffice. However, I decided to modify the original design by adding adhesive-backed velcro to the inner holes on top. The hollow design of the quadcopter weighs 15.95 grams in the software. With modifications, the full version weighs 23.76 grams. When using a slicer program with specific layer thicknesses (top and bottom at 1mm, outside at 1.2mm with three lines of 0.4mm width, and 25% infill), the weight decreases to 16.75 grams. I still prefer this design for several reasons: it's strong, lightweight, and has low drag due to its profile that reduces propeller-related drag (although not a NACA profile). The main wind force is vertical, making this design ideal for minimizing wind resistance. It also features a flat bed, which makes sticking to the print bed easier, and eliminates the need for support material during printing. Additionally, straps can still be used, but they will be stronger than before. As for generating a better profile, I attempted it but, unfortunately, hollow bodies are not yet supported in the software. Once I have more time and available credits, I'll post a new generate profile.
