Decorative Spoiler

thingiverse

I created this to give my robotic lawn mower (Husqvarna Automower 310) a high-performance upgrade, but the design can be adapted for any application. The spoiler's sleek design can be scaled up or down to fit your needs! Check out pictures of a downscaled version that's four times smaller than the original. I built the model in Rhino and included the original file, so feel free to modify it! Dimensions: 74x291x63mm To print this large spoiler, I had to split the wing into two parts, each measuring 150mm long. It's best printed standing upright, requiring 150mm of space in your printer or scaling down. To print successfully: Split print: "Wing_split_A" "Wing_split_B" "Leg_A" "Leg_B" Standing as a complete wing: "Wing_complete_noCapB" "Cap_B" "Leg_A" "Leg_B" Watch the robot in action: https://youtu.be/Er0d8AYZzWI Print Settings: Printer: Wanhao Duplicator 4x Rafts: No Supports: No Resolution: 0.1 - 0.3mm Infill: 50% Notes: I used Simplify3D as my slicing software, and the settings aren't critical for this print. I opted for a 0.15mm layer height and corkscrew mode (0% infill). A lower layer height will make it easier to sandpaper and paint afterwards if you prefer. If your printer supports Skirt/Brim, add that as two initial layers, 0.2mm from the part, with eight outlines when printing the wing. This will improve stability and adhesion. Printing the wing without caps/fins and support (Wing_split_A_simple.stl or Wing_complete_noCaps.stl) recommends using "corkscrew/vase mode," which yields excellent results. In this case, use Skirt/Brim to stabilize (see picture). Post-Printing: Assembling: Glue the two wing parts together for a strong bond (fine-tune the support beneath the wing using a small file if necessary) Optional: Sandpaper and paint the wing and legs for a nice finish! Mount the legs wherever you want them using glue or tape Mount the spoiler on your product using screws, glue, or tape If printing the whole wing standing upright, mount the top fin/cap afterwards. Designing This: I used Rhinoceros 5 to create this design. Based on a real spoiler picture, I designed corresponding wing profiles. Created a "loft" from these profile curves Designed the legs, fins, and support
