These are attached via M3x10mm self tapping screws to the bumper. Follow the steps below.

1) Remove the bumper by unscrewing the 10 screws holding it on underneath the vacuum
2) Gently lift the bumper up and out
3) Carefully remove the 2 screws for the IR sensor
4) Screw the 3d printed bumper onto the original bumper

Tip) Line the 3d printed bumper up with the first "pillar" of plastic on the inside of the original bumper (Ref image). This will reduce the chance of this addition from interfering with the IR sensors behind the lens

Tip) Be careful when trying to hold the two pieces together while fastening the screws.

Tip) Keep the drill's torque limit to its lowest setting to prevent stripping.
