This is the third version I've designed of my Kitchen Shelf Hook. I redesigned it to be a little more aesthetically pleasing (I think), and also made the actual hook a little narrower to make it a little easier to hang and remove things.
There are two versions. Ver3a has a shallower hook, and Ver3b is the same as my previous model. I've also uploaded 4 sizes for each version for different shelf thicknesses (12, 14, 16, 18mm). Feel free to request any others should none of these sizes work.
I've also uploaded a 3mf print profile containing all the different sizes so that you can just select the one you need and make copies according to your requirements.
