Summary

I liked some of the other utensil designs, but wanted something with more rounded edges so it doesn't snag on clothing. This design is attached with x3 M3x12 screws with a washer and nut.
The attached .3mf file modifies the hooks to be 100% infill for strength, and the filleted edges seem to add to the stability. I used PETG, but other filaments should work as well.
