Toranado Precision Geared Extruder X-Carriage for Prusa i3 w/ 8mm Smooth Rods

Update 8-29-2016 - Added CAD .STP files for both M3 Nut and Heated Insert versions.

Update 1-31-2016 - There is now an alternate version of the x-carriage that uses M3 nuts instead of the Brass Knurl nuts. If you'd like to go this route, print tpge-xcarriage-wm3nuts.stl and use that part instead.

This x-carriage is designed with the following considerations:

• Utlilizes the Prusa i3 format for 8mm smooth rods placed 45mm apart.
• A perfect mount for the Toranado Precision Geared Extruder that maximizes Z-axis print height. The TPGE can be found here: http://www.thingiverse.com/thing:1246951
• Can be removed or installed onto the printer without disassembly of the x-axis idler or x-motor mount.
• Contains an integrated X-axis belt holder.
• Uses the same mounting pattern spacing as the i3 Rework.
