I had attempted to build a RepStrap printer weeks ago using mainly locally available parts, except for the stepper motors (USA) and bearings (China). Total cost around RM700~RM800 (excluding the printing material).
It took me a few months to read up on the mechanical and electronic modifications since it's not from main Reprap branch. Still working out the programming kinks. The firmware isn't moving the motors properly as they should.
