This is a derivitive of "Platform Leveling Trick" by ScribbleJ. http://www.thingiverse.com/thing:6545 This version uses stuff that I had lying around the house. It uses springs out of a mechanical pencil (which fit perfectly over the bolts), to make it easier to level the build platform. It might take a little bit of the stress of the extruder nozzle, to prevent it from breaking your extruder, if it is laying down too much plastic also. Take apart 4 mechanical pencils, and remove the springs (I have only tried BIC pencils). Place the springs in between the wooden baseplate, and the build platform. Then just tighten, or loosen each bolt seperately to level the platform. :) Enjoy
