About this 3D model

This is an extruder mount I designed for attaching to a Prusa i3 x-carriage, such as the modified 4 bolt version featured on my page. It is currently used in the TubularBot 3D printer when a Magma hotend is installed. Works best with Greg's accessible extruder. It has an integral fan shroud that prevents the cooling fan air from blowing down onto the heated bed. It instead directs the air into a chamber in the extruder mount where it then exits through horizontal and vertical escape holes.
