Tiger Tooth

thingiverse

It's a traditional keychain model based on a massive classic saber-toothed tiger tooth. I suggest printing it at 10 microns with 100% infill density and a speed of 30 mm/s. Since supports aren't crucial, you can focus on sanding the finished product with progressively finer grits of sandpaper - it's essential to use high-quality paper for optimal results. Adding copper layers around the buttonhole is also a great idea.
