Post a fully-dimensioned 2D sketch of it (pencil and paper) and someone will model it for you.
As you say, FreeCAD has a steep learning curve. If it looks like the one above, drawing it from 3D solids that have Boolean operations performed on them might be easier than using sketches.
You could try OpensCAD, but if you want a facsimile of the one above, it might be tricky from a standing start. However, if you can live with a functional replacement, it becomes much easier: its body is a cube. It is then partially cut by a horizontal cylinder. At the base, a cylinder projects, joined to a truncated cone (in OpensCAD a cone is a cylinder), cut through with a cube.
