Jay made the smallest CNC plotter made by Laser cut parts which according to his blog cost about $20 to re-produce, this is really amazing piece of engineering:

I do wonder if something similar could be adapted for solder paste syringe and to make small solder paste spit machine which to eliminate the need for stencils for prototype runs.
