Simple to print, takeup spool I made for my Smena 8 camera, It needs only a small cut on film to work. first 2-3 perforations from upper row.
Cut in slicer at 37mm height. Print on flat surfaces, then glue. Layers resolution - highest available. No neet do waste time with eg 0.25mm layer.
PETG would be the best as it will leave some strings in film gap, keeping the film tighter.
Should work with Agat-18K Smena-2,4,6,8,8M Kiev-2,3,4 Contax-2,3
