About this 3D model

hello, I've been struggling for a long time with the fact that I don't have a place to put my school bag. I therefore took the opportunity to come up with a holder for the chair. I wanted it to be a bit interesting and stylish. That's why I chose the image of the thumb. But I thought it was too big and unused, so I turned it into a pencil holder. Then I also thought, well, what about the keys? and so I made a key holder out of a bolt. There should be enough clearance in everything and it should go together nicely. Nothing sticks, and it uses nothing but what you print.Let me know if it works for you too :-)Thanks.
