Thanks, lots of good information here.
I have checked my local library and they don't have one. Also I have tried some online 3d printing sites in Australia and shipping basically killed the idea.
For example I created a stl file for a ceiling fan control knob it was $5 to print and $12 to ship the product to me! A bit steep for a object 22mm x 18mm. FYI I have attached the file for those interested (not sure if it fits though never printed).
Hence why I'm looking at a cheap 3d printer, so I can learn all about 3d printing and something the kids can use as well.
