We will prepare all the parts before putting it all together. We start with the
extruder belt clamp/tensioner. Use m4x30 bolts and self-locking M4 nuts.
For the top bolt also use a small washer.
Get the extruder arm. Mount an M4x20 bolt. From left to right:
M4x20 bolt, small washer, extruder arm, small washer, small bearing, self-
locking M4 nut.
Don’t worry if the bolt doesn’t go fully through the self-locking part of the
nut.
Get the extru_base_pt_3. And mount the bearing: From right to left the
parts are:
m4x20 bolt, medium washer, plastic part, small washer, bearing, self-
locking nut.
Again don’t worry if the bolt doesn’t go fully through the self-locking nut.
