X-Carriage Mount Block

The X-Carriage block accepts the dual drive extruder design of Schematix. Schematix: Dual Drive Extruder (Fits E3D v6). I designed a kleat system to secure and tighten the belt. I used this on my Reprap Guru 3d printer which uses 8mm rods spaced at 42mm. Please use the .stl files for reference only. My intention is to provide a starting point for freecad users to customize and improve this design. Sadly I did this one while still using Freecad 16 so there are no bodies to work with. Freecad 17 uses bodies via the part-design menu. It's better IMHO. I have around 200 hours of 3d printing with this design. Big Thx to Schematix. Oh yea I often tap holes in plastic instead of using a nyloc nut. If you see a hole to no-where, assume I tapped it.
