For this build you will need (refer to photos):
You can reinforce both part fans by installing 31mm 2/4 PTFE rebar behind your hotend, using 2xM10 self-tapping screws (see last photo to see how it is mounted in front).
Keep in mind that this toolhead is about 3mm wider on each side than original Mini SB, in place where (sensorless on V02 at least) homing occures.
The author marked this model as their own original creation.
