Build is a mini CNC device. Attached picture and the travel required is 70mm. 35mm each way. The drawing attached is a portion of the full build and the travel is on the HGR 35mm each way on the grey base. Make sense?

I could easily put a Nema with a screw on the back of this and it would work. But it would be bulky and not pretty nor nice to look at TBH. Does anyone know of a better way to do this? I have thought of a vertical mount with a belt but that would not be ideal in the environment. So I am reaching out for some input before I end up doing what I know, and installing a Nema with a ballscrew it just seems so.... done before.

Oh and it does need to be accurate, well as accurate as any home built CNC device. Thanks in advance for input would be appreciated.
