I mean the fuirst image looks fine to me.

Do you not have files or sanding tools where you live ?

Print the first image and then spend about 20 minutes cleaning it up. Job done.

If you work the resin prints before final curing, they are really easy to cut and smooth.

I realise you just want to print and use.
But the reality is that a lot of the time, it's just faster and simpler to do a little filing and sanding :-)

Also if you bought the stl file.
get back to the person who sold it to you and complain.
Like everything else these days, they'll probably sell you their soul rather than have any negative feedback.
