What options do I have to extend my stay in Thailand without incurring overstay fines after my Covid-19 extension expires?

A user is seeking advice on extending their stay in Thailand for a few days beyond their Covid-19 extension expiration date without incurring overstay fines. Responses suggest that they can apply for another extension at the immigration office before their current expiry date, potentially allowing a further stay of up to 7 days if their application is not approved. They may also consider applying for a new 60-day Covid extension if they visit the immigration office when 30 days or less remain on their current stamp.
