A floating(ish) bookshelf designed with Fusion360's Generative Design tool. The shelves also connect together with a fun (to me) pseudo-kinematic interface.

The only version I have built is with the 'GD_WallBracket.stl' version of the brackets, but I went ahead and included a handful of the other solutions in case anyone wants to deal with the resulting support material goodness (and if you do, please let me know how it goes!)
