Center Point Marker - Replicator printable (Q87952)

This is a very cool center finder invented by http://www.thingiverse.com/hlyman. I rank this as one of the most interesting and useful things on the thingiverse. Certainly the backstory is the most compelling. I scaled it to 75% to fit the replicator bed. I also redesigned the pins to make them a press fit, thus eliminating the need for screws on those parts. I also redesigned the rotating brackets and control knobs to improve their operation after scaling. I put multiple parts in one file to speed up printing. NOTE: Scale the Right Arm file using inches->mm button or download the last file on the list which has the scale fixed already.
