If it's no trouble, just run the mouse for a day and change the running wheel every day.
You can buy one and keep it from your mother if necessary. It can be said that your classmate gave it to you.
If you make it yourself, use the bottom of a large coke bottle and cut it wider so that the mouse can escape.
If the problem hasn't been solved, go to the hamster and see how the DIY running wheel is made.
