Just put one of the M201 "2 in 1 out" printers together. ALL of the acrylic parts fit perfectly. None of them cracked or got damaged during assembly. Two rods slip into metal mounts. The holes were too small. In one case it as just the thickness of the paint and once scraped off the rod fit fine. The other one was that the rod was 8.04 mm in diameter. That rod was also bent more than I though acceptable. New rods are being shipped at this time. Customer service was good. Once they understood how I measured the bend and which rod it was they shipped.

There were a few minor issues that made this kit not "perfect" out of the box. 2 of the limit switches could not be tripped by the carriage with out extensions being made and installed. One of the hardware packages was mislabeled in the bom. A couple of the electrical connections were described in the instructions, but were easy to figure out.

I'm glad I bought the printer and if I had it to do over I would again.
