NOTE! I only have one hand on the end effector here. The other hand was holding the camera. In reality, you’d want to do this with both hands.

Line everything up and get the snaps as close together as possible.

One side at a time, apply even pressure simultaneously on both sides of the snap, directly over the snap in the area indicated with red arrows.

Repeat for all 3 sides.

The snaps may crack slightly but the end effector will hold (there are screws as well holding the assembly together)

Install 4x M3 x 12mm SHCS (if using auto levelling probe) or 6x M3 x 12mm SHCS if using FSR Auto Levelling.
