If you're looking for a F/LOSS tool for mechanical CAD other than FreeCAD, try solvespace [1]. It's definitely good enough for simple usecases (especially 3d printing and lasercutting where there's good standalone CAM flows).
EDIT: found an answer here: [1]
For purely mechanical parts where I don't have to repeat myself a lot, I found solvespace to be a much better solution.
