FreeCAD
FreeCAD is the preferred FOSS software used at Knox Makers for CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing). While you are always free to use other platforms you'll find that some of our devices are setup to integrate specifically with FreeCAD using add-ons & packages that have been designed in house to work with our devices. Additionally, peer support from other members will normally be easier to find if you are using FreeCAD versus other alternatives.
As of February 27, 2026 the preferred version of FreeCAD to run is 1.1rc3.
