the thumb rest of my sony rx100 m3 fell off, so i made a new one. this version is a bit bigger for the thumb and should add some extra grip compared to the original. print as fine as you can with 100% infill and glue in with double-sided tape. the fit is snug, at least with my print. but the model has some tolerance. may fit other rx100 models, but i can't confirm.
The author marked this model as their own original creation.
