Repair or replace dryer

Our dryer smelled like smoke earlier, so we took out the 3 screws holding the back panel in. There was tons of burnt looking lint, got that all cleaned up. Well we didn’t think it would be an issue but the entire drum is now off center. We laid it on its back and thought we got the screws back in correctly. Wrong. What’s the cost to fix this? Or should we look into buying a new dryer?
