This is a slight tweak of Michar11's autohelm holder.
I printed Michar11's version for a friend of mine, but it was a bit too thin, and the screw holes were not countersunk correctly to fit the screws from his original holder model.

This is an updated version, it's about 1 mm thicker so it works with the legs of the main unit, and it has countersunk screw holes.

It is possible there are several iterations of the real bracket.

I added the 1mm addon to the base of the holder, which also means that there are no slots behind the "wings" like on the original - However the slots serve no mechanical purpose and my 5mm thick version should be stronger.
