Jack the joints maybe touch them with sandpaper but don't remember having any problems. I thought my bricks came out pretty good, you could download one of the samples from the "3D Printing Repository" on this forum to see how you like them.
I did try several printers that my son had a which caused me to buy a Prusa MKS Kit which took 4 days to build. So has logged 72 days of running (that's 1728 hrs run time) with no problems (just make sure the slides stay greased lightly) and today DHL brought another Prusa but this time a Mini, took 8 weeks to get here. Haven't even unpacked it yet but expect good things there.
Here is the hotel I did, 100% printed (except the awning)
