The next step is to prepare the extruder. Remove the printed plastic base on the Bu-
daschnozzle ( Figure 5.41 , the base is printed in black). You may want to keep this black piece
so you can direct mount your extruder to the x -axis in the future. Now atach the extruder
mount (blue piece) to the Budaschnozzle using the same screws and tighten the whole Bu-
daschnozzle down as shown in Figure 5.42 . Atach the Budaschnozzle to the x -axis using two
M4 × 20 screws, nuts and washers and your printer should look like it is coming together as in
Figure 5.43 .
