Use the tables below to easily order all of the parts for a FarmBot from our recommended suppliers. Clicking a component’s name will jump you down the page where you can see that component’s tech specs, view drawings and photos, find links to other suppliers, and download CAD models and manufacturing files in various formats.
You can also bulk download the entire CAD library and all manufacturing files.
We recommend SolidWorks
FarmBot Genesis was designed natively with SolidWorks 2014. Using SolidWorks 2014 or a newer version will provide the most seamless experience if you are interested in modifying the 3D part files.
We're here to help

Don't forget about hidden costs
If you’re thinking about building a FarmBot yourself, be aware that the prices in the tables above do not take into account shipping fees, taxes, and minimum order quantities. If you build one FarmBot on your own, expect to pay an average of 30% more for the components than the listed prices.
Also note that the grand total does not include materials for supporting infrastructure such as a raised bed. The type of infrastructure you decide to install could cost as little as $10 for small wood posts in the ground or as much as $300 for a high quality raised bed with soil.
Overall, expect to pay between $2,000 and $2,500 to build a FarmBot on your own.
Extrusions
Track Extrusions
Track extrusions are the primary structural component of the tracks sub-assembly. They can be combined end-to-end in order to create longer tracks. The gantry v-wheels roll along the track extrusions, allowing FarmBot to move in the x-direction.

Gantry Columns
The gantry columns are made from aluminum extrusions. They can be scaled to be taller or shorter to satisfy your needs. The two large spaces inside the columns are used to conceal and protect the GT2 timing belts that run along the tracks and up to the gantry pulleys.
