Slide Strike Pin and Spring combination from earlier in the build process onto the Auto Probe Body.

While compressing the Strike Pin, place the standoff on the flat side of the Strike Pin. Note: newer versions of this kit ships with 2 standoffs. Use the shorter one for the Mini Kossel, the longer standoff for the Kossel Pro.

Insert M2 x 10mm FSC from the countersunk side of the Strike Pin, tightening screw all the way with the supplied 1.3mm hex key. NOTE: newer kits will ship with blue thread locker pre-applied to this screw.

NOTE: It is important to lock the stand off in with no movement, by cranking down on the M2 x 10mm as tight as you can. Failure to do so will result in the probe falsely reporting a triggered touch.
