My first 3d printer was an MKS3+ and I'm very happy

Thank you to the Prusa team. I started assembling the kit on Friday afternoon and finished Saturday afternoon. Manual and handbook are great.  I spent about 12 hours assembling. I was very thorough and my final calibration value was .05 degrees. I used 123 blocks to check squareness when assembling the frame. The blocks also helped a lot trying to insert the nuts into some harder places. I only had to disassemble the extruder once because I forgot a single square nut (step 5) for the top cover(step 25). I do not recommend starting the extruder at night and finishing in the morning.

One strategy I found effective was threading the nut partially onto a longer bolt. I then used this longer bolt to seat the nut in the recess. At this point you can push the nut in and know that your sides are parallel or you can grab the nut with a screw from the other side as suggested in the manual. It takes a bit more time screwing and unscrewing but I got everything seated with out any issue. Small round file helped a lot to clean up some holes. I think it would be worth adding to the tool kit. Flat file would be good too but not as necessary as round.

The software was very intuitive. Took about 15 minutes from opening PrusaSlicer to having my g code. 

First real print over Saturday night is the power supply brace. 11 hours over night no hiccups. I did run some of the prints off the SD card in the evening and they turned out just the same.

Overall I couldn't be happier with my first 3d printing experience.
