Modular towel hook

I am new to 3D printing and wanted to design my own thing. I decided to design simple towel hook in Tinkercad because all of the hooks in the bathroom were broken.

Except one all of them had broken hook. Therefore i was thinking about this modular solution where hook could be easily replaced when it breaks without having to mount it out of the wall. On top there is an option to add and remove a figure you want.

I tried a bull, a bear and pikachu so far. I attached the "Hole object" which can make hole into any figure so it can be attached to this hook.

I was printing with 70%infill, 3 walls, 4 top/bottom layers and it holds big towel nicely.

The figure i printed with 0.8 line width, one wall and zero infill, tree support
