3D Printed Rubber/TPU Cat Toy on my Ender 3
This shows a TPU (Thermoplastic PolyUrethane) printed cat toy. I printed it on my Ender 3. It printed really easily. Before I could successfully print, I needed to convert the printer to direct drive.
This was my first print with TPU. TPU filament is weird. It bends like a piece of cooked spaghetti. So pushing through the bowden tube wouldn't be practical. It isn't stiff enough to push the whole way through it. On the direct drive, it's fine.

A 3rd party direct drive upgrade kit. Good stuff, but you'll move your extruder stepper and hot end over to it. A little more work, but not difficult to do with simple tools:
