Take 'n' Toss Kids Sippy Cup Lid Clamp

thingiverse

This device is designed specifically for parents with little ones, aiming to prevent messy situations caused by sippy cups that toddlers love but struggle to handle. The clamping mechanism ensures the lid stays securely in place on cheap disposable cups, eliminating spills and frustration. My own son had this exact problem - his milk was constantly leaking onto the floor due to the lid popping off whenever he dropped the cup. This design is a direct response to that issue, tailored to fit Take 'n' Toss brand sippy cups perfectly. To assemble, simply slide the bottom sleeve over the cup and attach the top cap to the lid. As they're threaded together, the mechanism tightens down, guaranteeing the lid stays put even when dropped. To minimize weight while maintaining effectiveness, I recommend printing with a low infill percentage.
