General purpose bag clips
Available sizes: 50mm, 100mm, 150mm, 200mm, 250mm. Feel free to request longer or thicker variants, or make them yourself using the Fusion 360 project file included.

I needed a bag clip that would work with PLA and that would print in place.
There is already a design very similar to this one on the site (https://www.thingiverse.com/thing:330151), but I hadn't really browsed the site for clips before making this.
Seeing as I've made this anyway, I am using this one for all my bag clip needs!
I recommend printing the hinge portion with enough perimeters to that it's made pretty much entirely of perimeters. You can achieve it with multiple processes on S3D or probably with modifiers on other software that supports it, such as Cura or Slic3r.
For the longer clips it may be hard to print without adhesion aids especially on warped print beds, without mesh bed leveling. Though, especially brims, are very annoying to fully remove due to the shape of the model in some areas.
Short clips tend to be hard to open, need to figure the right grip out, or filing a small amount of material off of the cantilever snap joint.
I hear that PLA can deform when kept under stress. This actually happened to me with the longer bag clamps, they can deform when clamped around thick or folded over bags.
It may probably be fixed by changing material, or editing the clip to be thicker, which you can do yourself by downloading the provided F360 file. Alternatively, you can request an edit to me.
Make sure to pry apart the two separate bodies first before trying to use the clip, it's stupidly easy to twist the hinge until breakage otherwise, but once separated it works really well without breaking.
You can do this using any thin hard object, maybe credit cards too.
