The T-33 was originally scaled for my Behotec J66.
Later on, Sara at Wren provided their technical drawings. The Wren is drawn on the plans. It actually fits better because it's just a bit smaller in diameter than the J66.

It will also fit a ducted fan by moving the mounting rails further apart, it's a tight fit.

I can re-scale and print to just about any size. Even the French Giant Forte class!
