About this 3D model

This design is based on the one published by whpthomas at http://www.thingiverse.com/thing:41090. However after printing his, I realized that indicators with the stub on the back for mounting to a magnetic base would not fit, so I simply modified his design to fit my indicator. UPDATE - Feb 4 2013 I uploaded a new STL with a cutout to accomodate the version of whpthomas' Extruder Upgrade http://www.thingiverse.com/thing:42250 that has the tab on the pinch arm.
