Unfortunately - doesn't deliver to Australia.....

Yes they do, I got mine delivered in 5 days from china - but that doesn't mean I recommend buying one.

These feet? http://www.thingiverse.com/thing:916254

The feet we printed are very similar to those but have more plastic at top
to hold them on printer better, when lifting up or moving printer.
And they used pipe-insulation for the spring, not many metal-springs.
(insulation can be purchased at hardware stores)

This is feet we printed with Black PLA to match printer color
and they work very well !
(Since we already had the pipe-insulation they were easy to assemble)
These will fit several different models and makes of printers
