I got a comment when asking people on maker world what I should make and @UltraModern3D commented you should make 24 free to sell cat bookmarks, and I used image to 3d model for the cat face and made the cube was made in Bambu studio.

I had to make batches off 12 not 24(more efficient) because Maker World limits print profiles to 200 MB and 24 was 340.7 MB.
