Project Overview

This project upgrades the SainSmart PROVerXL 4030 V2 with HGR15 linear rails and CNC-machined adapter plates. I modeled the parts and assembly in FreeCAD, created technical drawings for fabrication, planned the machining-oriented plate design, and produced a Blender render to present the finished upgrade package.
