Parametric Nalgene replacement cap strap

A simple replacement for the Nalgene 1,000ml bottle cap strap, leash, or tether (whichever is your preferred nomenclature). I've included a parametric Autodesk Fusion file in case you want to adjust the sizes to suit your specific water bottle. Simply open the Change Parameters menu, set BottleNeckDiameter and CapLoopDiameter to the inner diameter sizes of your old strap and you're ready to export and print.
