I have a working chairmanone dd43, works decent. I was curious if anyone knows of a 43 frame that takes dd rails and is stronger than chairman’s, ie thicker. I want to print it in cf nylon, but iv done it with chairman’s design and it broke because it was so thin.

It doesn’t take dd43 rails, but I think you should really take a look at PY2A’s 43X frame (s well as his others). They are very close to OWM with some minor tweaks, but very sturdy imo. I do like his rails better also.
