This is a remix of Sharkz by muzz64. I can't add his version as the source because he didn't allow it. Please abide by his other desires.

I made the bite deeper with more aggressive teeth and more spring tension. This was optimized for PETG.

This makes a good bag clip or toy.

Make sure your bridge settings are dialed in. This should have no bridge problems. You can have Cura add a small support on the build plate only for one bridge. See the attached Cura pic to see the small support shown in cyan.

I print it at 110% scale in X and Y, 150% in Z. 3 walls and 30% infill. I print these at 0.3mm layer thickness for speed.

Enjoy and look at muzz64's other creations. I like his Piranhaz and Minisaur. They work as great bag clips for me when printed at the right scale and settings.
