This project printed quite well. My printer's not the best, so I did have an issue with the holes on the screw posts not being consistent in inner diameter. Nothing that a little playing with a drill bit won't fix, though. I also had to a little shaving on one of the edges to get the board to fit in just right, but this is also probably due to my printer's lack of calibration right now. I now feel much more confident that I can set my nucleo down somewhere and not short some pins, etc. Also, it adds a little weight and stability to the board so the jumpers don't have their way with it!
