So I have collected the 3 files that I have made to get the Geeetech 3 in 1 mixing hotend up and working in an i3 style printer. the i3 style home built printer i made these parts for uses Geeetech i3 pro B printed parts for the X and Z and so this carriage will fit any i3 style printer with the same spacing between the 2 smooth rods as what is in the Geeetech i3 printers. I still have to design a layer fan but i did leave a place and 4 holes to attach said layer fan when I get it drawn up. And I will add it to this: Geeetech 3 in 1 Mixing Hotend Universal i3 Mount by AutoWiz - Thingiverse
