Yes...I know it's been a while since the last post but I've recently started playing around with freecad
Partly to start getting geared up for PiWars and partly to get the ender 2 gainfully employed and not sat there looking forlorn.
It's certainly a bit of a giggle to get the hang of it but it's looking worthwhile to learn.
A nice intro to Freecad wrote by Jo Hincliffe (@concreted0g) can be found in issue 25 of Hackspace Magazine...or by clicking here
Another great resource are these video tutorials on this youtube series by Power Playground
