NOTE (5/28/18): I’ve been told there are some sizing issues for the thumb switches and possibly the bottom half. I suggest holding off on printing until I can verify and correct these issues. Thanks.
Iris keyboard case. Print as they are oriented, with supports. There is enough clearance to socket your pro micros.
Supports required for the outer shells and they should be printed top-side down. I have them oriented how they should be printed. I printed with 3 shells all the way around.
