About this 3D model

https://www.youtube.com/watch?v=e109tYzCs8A This work is based on Andy Haer's work : http://www.thingiverse.com/thing:215294/ I've modified his work to fulfill my needs of a heavier glass bed. What i've changed : - remodelled the above 3 parts completely (to remove holes and avoid printing problem like in Repeatier) - extended jaw's length - changed bed levelling (for levelling from below) - toughened parts to support glass - added M3 hex nut knob to tightened bed levelling See instructions.
