Ender 3 Z-Axis Spacer

thingiverse

This print is used for taller prints so that the cables going to the extruder and the bowden tube do not get in the way of the top aluminum bar, but it does not affect smaller prints. To attach it to the vertical bars, I used the exact same screws that were originally attached to the top of the machine. To attach the top aluminum bar to the spacers, I used four of the same kind of screws along with four nuts of the same size (5 mm diameter) to hold them in place. I only printed the parts with three perimeters and it is plenty strong, but feel free to use more if you are nervous about it being to weak. There are also no threads modeled into the holes, because the nuts will hold everything in place.
