You are tasked with designing a landing gear that mounts to the 2024 2025 competition drone airframe, attached here:

Constraints
- Your landing gear should be made in its own subassembly, please do not build it directly in the x-frame assembly.
- Your landing gear must be mounted to the main x-frame tubes, you may add mounting holes for this.
- You may use the same size carbon fiber tubes as the x-frame, 22mm outer diameter, and 20mm inner diameter.
- Your landing gear should be designed to break at the joint connecting it to the main frame if it has a hard crash, but not on a normal landing. The purpose of this is to protect the carbon fiber tubes. (This is hard and we’re not looking for it to be perfect, just have an explanation in mind as to how your design meets this)
- Using a density of 0.002 g/mm^3 for carbon fiber tubes, 0.0006 g/mm^3 for any 3D printed parts, and 6061-T6 aluminum for aluminum parts, the total mass of your landing gear should be below 500g (you can modify the materials assigned to your part to have these densities). The mass of your assembly can be viewed using the Mass Properties panel in SolidWorks.
- Common materials that can be used include carbon fiber tubes, carbon fiber PETG blend 3D printer filament, and 6061-T6 aluminum but you are welcome to use others! Just make sure to assign your materials properly so we can check the weight.
...
- Drawing uses the WARG drawing template.
- If the part is to be made on a mill ordinate dimensioning is used, with limited exceptions for pitched dimensions of holes, or to use proper GD&T for locating geometry.
- Drawing has millimeters as the primary dimension and inches as the secondary dimension. (Note that this is part of the WARG drawing template!). The exception to this is datums, these should have only one dimension (since both are 0). Secondary dimensions in inches are not required.
- Greater precision than 0.00mm & 0.000in dimensions is never used.
- Wherever reasonable, circular dimensions are given as a diameter, not a radius.
- All circular parts and features have center marks & center lines.
- All hole callouts are made with the hole-callout feature, and the generated callout is not modified except with valid reasons. To do this, your model must use hole wizard!
