Some Sumsung monitors haven't holes for VESA-brackets, so I modeled adapter fot this type of monitors, so now you can print it and mount your monitor for usual VESA-bracket.
I used PETG plastic, because model made of it is durable and springy as well.
You need to print 12 big pins and 3 smal ones. then glue two parts of adapter using pins to made connecton more strong.
Adapter has 4 holes for M6 bolts.
