Revised Wade's extruder

* files removed due to new legal terms***8

Here is my revised version of Wade's extruder block.

-Revised the inset area for the 608 bearings
-revised the filament entrance
*Added - Captured the bolts that hold the PTFE
-Smoothed the part edges.

I included a 3D Pdf that you can open and rotate in 3D!

For those interested in the parts shown in the picture, they where printed solid at 0.007" with smart supports on a Dimension Elite 3D printer, build time was 14hrs.
