About this 3D model

This is a single-piece hand grip that goes on a 5oz Medela baby bottle, to help your little one learn to hold up the bottle herself. It goes on underneath the bottle lid, and three small crush-tabs on top automatically adjust to the bottle and lid, for a snug fit regardless of printer calibration. The design has been graciously (and sometimes not-so-graciously) beta tested by my 6-month-old daughter. Obviously, let your baby use these grips only with supervision; they are for learning, and not intended to be a chew toy.
