Version 2 is stiffer and works a bit better!
If you have Invisalign, Smile Direct, or other aligners, it can be difficult to remove them sometimes -- especially if you have attachments that increase the tension in the aligners and create undercuts. Removing these incorrectly can more easily snap off the attachments, as I learned the hard way. With these little hooks, you can remove them inside out (on the top) and slowly, a little at a time, reducing the risk of damaging aligners or attachments.
These are smaller than most commercial hooks and fit into an aligner case very neatly.
Print with PLA for a little stiffer tool. Keep away from children!
