I have Mamiya 645af which had focus mode selector lever gone missing.
I tried eBay, contacting second hand camera stores local and overseas, and camera shops in Japan but it was impossible to find just that missing lever.
My only and last option is to 3D print. I contacted the local 3D modelling company and got a reply saying they could give it a try if they know the exact dimensions. I am wondering had anyone tried something similar to this? If so, how have you found the exact dimensions.
