There's also Fusion 360 that's free for personal use. SolidWorks is better and worth $50 / year if you use it a few times, but for a one-off project, Fusion 360 is pretty good.
Really wish there was a non-subscription Solidworks though.
You should also be able to export an f3d archive as long as it’s a standalone design (ie not linked to other designs).
Give me a copy of SW 2012 and I can model anything technical I can imagine.
