Hello Plombikas,
You may choose what you 3D model in Fusion 360 and submit to the D4A challenge. Please make sure you carefully read the posted guidelines. I've also pasted them below. If you are unsure about specific guidelines please click the links - they'll take you to more detailed explanations.
Thanks,

Design for Autodesk guidelines:
- Project must be created exclusively using Autodesk Fusion 360.
- Project must include 15+ individually named1, unique components2.
- Project must include mechanical details describing the interior as well as exterior of the model.
- Project's components must be combined and submitted as one .f3d or one .f3z file. Please see Tips for Exporting files from Fusion 360.
- All individual components must be modeled by you. You cannot import existing CAD data into your design, with the exception of components from McMaster-Carr3.
- You must be the sole owner of the project and all materials submitted to Autodesk. Projects sponsored or funded by third parties may not be used. No third party (including your school or project sponsors) should have any rights to materials you submit.
- Projects comprised mostly of extruded rectangles (Ex. rectilinear furniture or architecture) will not be accepted.
- Projects must demonstrate proficiency in at least two of the following criteria:
- Free-Form modeling
- Traditional parametric, sketch-based modeling.
- Functional Joints that can be manipulated with a mouse to convey motion.
- Components and bodies must be named to be counted. Ex: "Component1, Component2, or Body1, Body2..." will not be counted.
- Identical components like wheels will be counted once. Additionally, the components within a wheel (bearing, hub, tire, air valve, etc.) will each count once.
- Pre-built components such as nuts, bolts, and brackets may be imported from McMaster-Carr, but multiples of the same will only be counted once.
