The RedCat 51 telescope can be mounted with the ZWO EAF autofocuser, see https://www.thingiverse.com/thing:4683480. Note I bought the EAF mount before I got a 3D printer, so this is not a remix of thing 8683480 but you can easily combine those.
When the RedCat 51 telescope is fully equipped with autofocuser, camera, filter-wheel, off-axis guder etc. it is difficult to hold, so I made this handle which is attached to the telescope base and thus allow to safely operate it.
