Imagine you're in a choir, or a soloist vocal musician, and you need a clip that holds your 3-ring binder open for one-handed holding that doesn't strain your hand. This might be the binder opener clip retainer-ey thingy you need! And maybe they're already around and I just don't know what they're called...
Anyhow, this model should help accomplish that!
The Version 2 model fits 3-ring binders with a ~22mm wide ring base and the binder walls being no more than 3mm thick. It has a 130-degree bend which was actually a bit too much for my taste.
The Version 3 model (Untested) fits 3-ring binders with up to a 30mm wide ring base, with binder walls no more than 4 mm thick. The bend has been adjusted to 110-degrees for a space-reduced size if you're in close proximity to other choral members.
You should also be able to find and copy the model for free in OnShape's public file repository by searching "Binder one-handed holder". (Don't judge the way I extruded it, I accidentally designed the base of the clip backwards 🤦) Then you can edit it to better fit your needs.
Remakes are encouraged! Please post them in the comments as well because I'm still not completely satisfied with my version and would love to see some improvements!
