spring clamp with teeth

thingiverse

I was impressed by the original spring clamp design, so I decided to modify it and add some features from other nice clips that I've collected over time as promotional swag. Specifically, I rounded off the edges and added teeth for extra grip. To make the design more accurate, I scaled it up to match what I saw in the pictures. This modified version was inspired by this variation: https://www.youmagine.com/designs/simple-spring-clamp/. For the spring itself, I highly recommend using ABS or HIPS material. PLA tends to break easily and snap under pressure. It's worth noting that the spring should be a bit shorter than what it is currently.
