After pulling many a hair out trying to make modifications to existing carriage file (every version I could find), have given up and began to just re-CAD from scratch. As proof of concept, made universal tool mount mods to carriage in Blender, but as a back-up I'm doing a super simplified mechanism as well in FreeCAD.

For Simple Extruder, I also started from scratch to build a replacement for the extruder spring base bracket that will also include wire org for the quick attach wiring, and a place for the toolhead mount. This should work for vertical or horizontal mounting, whatever we decide.

Working on Simple Extruder and Universal Toolhead Mount. Note also that D3D_Simple#Part_Library has more.

  Working through FreeCAD - Export issue - even trying to compile from the base files I pulled from this - Universal_CNC_Axis#Universal_Axis_-_Working_Document. FreeCAD file - File:D3D Universal Carriage v1910.fcstd

  UTA dev - Forked from Ferdi and was able to export. Got one side of the holes exporting properly, but don't know what issues on the other side - showing an error, but fully constrained code
