My setup:

Schneider Kreuznach Componon 28mm f2.8 reverse mounted on the hood thread (M37x0.75)
Tube lens: Carl Zeiss Jena 3.5/135mm (M49x0.75)

It covers a full frame with noticeable vignetting at full aperture on the tube lens.

Printed with PLA, 0.6mm nozzle, 0.1mm layer height. The thread came out very nicely.

I painted it black.
