21, New design of latitude adjuster:

The adjuster screws of the latitude angle of the EQ6 mount is of the same bad construction as of my HEQ5 mount. It's big risk of the camera or other devices hit these screws because they protrude out a long way. On my HEQ5 mount I replaced the North latitude screw with a shorter M10 and 3D-printed a new "hat" for it. Now I do the same for my EQ6 mount, the South screw I can remove because its function is nothing when living at altitude 60 degrees or higher.

Latitude adjuster screw:

This is the original screw, for sure okay for they who live in Southern Europe, but not up here in North. Big risk that the cables get stuck here or when delay the meridian flip the devices can smash it and be destroyd.

With a shorter M10 screw the problem is much less. The length of the screw is 40 mm, but depends at which latitude you live. Much safer now and very simple to do.
