==To modify the carrier==
You might as well just import the stl file into whatever cad application you like. Currently, the freecad file for the carrier is not very useful as a "source" file. It's just a mesh pretty much the same as the stl file for printing. Re-drawing the model from scratch in either freecad or openscad is planned. Then that will be a more useful source file for the model to make future changes from.
==To update the 3d model in the kicad file==
*Export a STEP file of the new carrier to .../NewWidget/000_LOCAL.pretty/3d/foo.step
*Open .../NewWidget/foo.kicad_pcb
*:footprint editor > 000_LOCAL > pcb2molex8878
*:footprint properties > "3D Settings" tab
*:folder icon > browse to .../NewWidget/000_LOCAL.pretty/3d/foo.step
*:save footprint, exit footprint editor
*:select the footprint in the main pcbnew display > right-click > Update Footprint
The 3d viewer should now show the new carrier.

This is a 3d-printable plastic carrier and matching empty PCB template to fit in the carrier, and both together fit in the option-rom socket in Tandy models 100, 102, 200, & 600. (and any other machine that has that same socket, such as Epson PX-4 & PX-8)
