The arm in the example may have slight differences (especially at the gripper), depending on the batch.
Do not use a self-tapping screwdriver! The parts are made of acrylic and can break if you're not careful! Some holes are smaller and others larger in diameter because in some of them, screws are threaded into the plates (the hole is threaded when screwing in), others are larger and allow free rotation of the screws.
