The requirement parts and option parts. - You can go with just requirement parts and keep the cost as low as possibe(about $100) or go a little fancy upgrade options parts(about $250 total). - ~~I will try to work with vendors to make upgrade kit if the demands are high enough.~~ Frame kit will be made :) - Fasteners are auto generated from the assembly CAD.
