This print-in-place locking bag clip has been designed so that it can be printed without supports, has a fun curvy shape, uses an outward angled handle for easier one-handed use, and is a nice size at just under 6 cm when closed.
I'd recommend you set the “Strength→ Wall Loops" option to at least 5 for increased strength. In addition to the STL, I'm also attaching the Fusion360 file if you'd like to make adjustments.
The original “Cam Lock Bag Clip.stl” (which I'd still recommend you start with if you're printing in PLA) is designed with a .2 mm tolerance around the pivot joints. If you have trouble with the plastic fusing in your print conditions though or are printing in other materials - such as PETG, I've now also attached two versions that increase the spacing tolerance slightly (.3 mm and .4 mm) which you could use as an alternative.
This is a complete from-scratch design, but there are many great cam locking clips. Although notably different, I've marked this model as a remix of the very cool model that ‘jfedor’ did which used a similar approach for making a clip printable without requiring supports (which itself was a remix of Andrei's popular version that does require supports).
