About this 3D model

I have three things, 1) An absolutely insane 7 week old kitten 2) A LOT of cardboard tubes from vinyl rolls 3) A 'crafty' fiancee who won't let me throw anything out! So we set out to design a cat toy with one of the larger tubes, with holes cut in which will be filled with toys, balls, etc. This is one of the end plugs I whipped up on Tinkercad for this purpose with his name, and a few random shapes recessed into it!
