I usually use Fusion 360 when I design 3d models but I have decided that for my youtube channel I am gonna show how easy tinkercad is to use. I am also gonna show case how this same design can be easily created in Fusion 360. They came out great and can hold a bunch of different rings and stuff. I will be making one that is more appropriate sized for a watch and bracelet.
