Breathe, breathe, breathe, you will get there. It may seem a little daunting at first but you will get results with a little patience and determination.
Make yourself acquainted with the SnapLinks page. It contains many useful references.
Fusion 360 and like CAD products are only required when you start to design your own parts…
May I suggest that you get started with existing models. There are many projects in Thingiverse there is even a Thingiverse SnapMaker Group
Select projects fro here to get started with. There are many neat add-ons fro your Snapmaker there. Try this one to get started with [https://www.thingiverse.com/thing:2722552](http://Christmas Gifts).
There is much to learn, so take your time. It will be trial and error for awhile.
Keep having fun…BTW I am in Brisbane. Maybe some Sydney Snapmaker users could drop in and help you get started for a coffee or a beer.
