Seiko VH31 / Miyota 2115 movement holder for Seiko NH34 NH35 NH36 NH38 watch casees

Instead of using mechanical movements for watch builds, I wanted to use quartz movements like the Seiko VH31 and Miyota 2115. Since both quartz movements are similar is size and shape, this casing ring will fit both of them.

I designed this from scratch using CAD. I wanted a movement holder that was quick to print for my seikomods.

There is an STL for 28.5mm and 31mm dials. The 31mm version was for a Seamaster homage build.
