 # KiCad 3D Models
 This repository contains 3D models for rendering and MCAD integration, for use with [KiCAD EDA](http://kicad-pcb.org/) software.
 The model needs a mechanical model source (a manually-modelled or script-generated file); its WRL counterpart file must be obtained as a conversion from the MCAD model
