FINISH MOUNTING
Insert the M4_80T_Wheel onto the GT2
pulley and press it flat to the guide.
Add 5 M3x8 BHCS to secure the wheel in
place. Gently tighten the screws in a star
pattern (skipping every other screw) until
the hub is snug. Don’t overtighten, you’ll
strip the plastic, or worse, the pulley!
