3. Gantry


The gantry is configurable for an AWD version and a 2WD version. The only difference between the two configurations is the rear idler mounts. On AWD they have an additional Nema 17 integrated in the design.

Placeholder parts

The Mellow VzBot kits come with placeholder printed parts on the gantry which allow the gantry to be shipped as a complete assembly. These parts need replacing with your own printed parts. Further instructions can be found on the placeholder parts page.
