About this 3D model

This is a replacement X carriage for the Orca 0.3 (it may work for the 0.2 or 0.4, I dont have those machines so its not tested there). It is printed in 4 parts and is screwd together with M4 studding. I have included the fan mount and blower duct that I am currently using. Not all of richraps extruders derivatives will work as the hole size is constrained by the X bar spacing in the oposite direction to the original. The source is in Alibre (Ive not given up openSCAD, but I need a more flexible design tool), sorry I don't have the capabilty to export it to anything but .stl **The latch is Richrap's origional duplicated here for completeness
