I've been updating my profile on grabcad this week. An useful 3d engineers community (like 3dvia) with thousands of 3d parts to download. A great source of parts and inspirational and impresive models. On my Grabcad profile you can download all my models that I uploaded along this week. I´ll update it futher with next parts I´ll model with Solidworks . If you don´t have an acount I recommend do it. Great page, lot of parts and good staff.
