My old suitcase lost a wheel, I couldn't find an official replacement part, I couldn't even find the brand “Daniel” online, so I made a new one because I would have hated wasting a whole trolley. It suprisingly worked flawlessly.

New wheels go less than £5 on Amazon.
Print flat, glue together around the frame stud, let it dry, mount the wheel, add some glue to the thread.
