Any tips getting into mechanical design ? I love designing PCBs, creating a schematic, then laying out the component and traces in the most elegant way is very satisfying. However when it comes to 3D stuff I wouldn't know where to begin.

Download Fusion 360 (probably the easiest of the serious programs and free for hobbyists), and start playing around, try making some enclosures for your PCBs copying features from existing objects around you.
