After a few grueling hours at hardware stores and even a specialty nuts and bolts store, i managed to find some threaded rod and a slew of different sized washers nuts and bolts. A couple of hours of build time and I've constructed the frame:

Heres the frame of my Prusa, patiently waiting for parts to arrive...

Unfortunately it is proving quite difficult to find the appropriate smooth rod needed for linear bearings in Christchurch, so she's just going to sit there looking pretty until i can source some. (the alternative is 30 USD + 30 USD shipping, which is a bit of a kick in the butt considering the idea is to construct this as cheaply as possible)

Once i have the smooth rod, i'll just be waiting for the linear bearings from ebay... then the stepper motors - which i don't exactly have funding for at the moment... then the arduino and RAMPS... then the hot end... this is going to be more expensive than i originally anticipated.

Now i just need to sit back and play the waiting game.
