Lite-On LTC-4724JR

This isn't really intended to be printable (though you could render it to STL and slice it), but I put it together to use with KiCad. This is a 3-digit 7-segment LED module, modeled in OpenSCAD from the dimensions given in the datasheet: https://media.digikey.com/pdf/Data%20Sheets/Lite-On%20PDFs/LTC-4724JR.pdf I exported to .csg so I could import it into FreeCAD to convert to STEP and VRML for KiCad. While the component was modeled 1:1 (mm) in OpenSCAD, it wasn't loading properly in KiCad without tweaking the rotation and scale values. By rotating -90° on Z and scaling by 0.3937 in FreeCAD (to scale, select "Draft" mode, clone the model, and scale the clone), the exported files are suitable for use in KiCad without further adjustment. I tried scaling and rotating in OpenSCAD, but that stripped all the color out of the model when I imported it into FreeCAD...kinda forced me to learn a bit more of FreeCAD. :)
