The Lid Lasso

thingiverse

The Lid Lasso helps you keep up with your bottle top. If you've ever lost the top for your water bottle or soft drink bottle in the car, you know what it's for. Every bottle should be equipped with a way to stow the top while the container is in use, but until the bottle makers start doing it, it's up to 3D printer enthusiasts like us to lead the way. The Lid Lasso is designed to be printed with Ninjaflex TPU. Unless you've tested another flexible filament for elastic properties that compare to those of Ninjaflex, Ninjaflex is the only one that is likely to work. It's amazing stuff for the price. Most flexible filaments that are rated at 85A shore hardness as is Ninjaflex are actually much less elastic, so they aren't appropriate for the Lid Lasso. Each Lid Lasso consists of two pieces, a grip and a stay. It may be possible to print the stay using a less elastic filament, but Ninjaflex will probably be needed for both parts. The Lid Lasso will be almost useless if printed from filament which is too rigid. I've included the Lid Lasso grip in 4 sizes and the stay in 3 sizes. Those should work for a range of bottle sizes and types. The one I use the most is the Medium Grip and Medium Stay. That size is good for 12 oz., 16.9 oz., 20 oz., and 2-liter soft drink bottles. The Small Grip and Small Stay combination work for most single serving drinking water bottles that I've used. See the YouTube video for usage instructions.
