thingiverse
Here it is a M39 and M40 ISO adapter for classic Soviet lenses like Helios 44 and others to Nikon F. I printed without support, and it works fine. You can see photos of this adapter and photos from Helios 44 at my Instagram @daenmart Any questions = to direct instagram. =========================================================== Всем привет это адаптер для Геликов с резьбой М39 (М40) на Никон Вам еще надо будет сточить до стекла заднюю линзу объектива.
