About this 3D model

This part is fairly specific to my build. It is likely it won't work for most other setups.That said, I used this part with x-ends very similar to Pointedstick's, his x-carriage, and a Wade's (Greg's) extruder.http://www.thingiverse.com/thing:16397http://www.thingiverse.com/thing:16291Hopefully the pictures make clear what is going on here.This part is sized to fit the endstops provided at store.mendelmax.com.
