      @dc42 I have now done an adapter that maintains the 12mm spacing of the magballs

      The carriage adapters look like this

      I played with the offset, settling on moving the centre line of the studs 7.5mm from the base of the triangle. This gives very close (within 0.02mm) spacing of 81mm for the arms, requiring a 13mm spacer on each side of the carriage. As you can see, this gives plenty of room for the orbiter 2 mounted with a straight vertical filament path.

      I have printed these in nylon using 80% infill, which seems to give a slightly better result than PLA .

      Not much experience printing with this setup yet, but the initial impression is of increased precision over the 55mm arm separation.

        @adrian52 thanks. Wider arm spacing is generally preferred, because it provides greater rigidity and less sensitivity to small geometric errors.

          @dc42 I should have done my homework. According to the reprap wiki here , stability decreases linearly with ball gap, but increases with the square of arm gap. So compared to the standard geometry, keeping the arm gap decreases stability almost threefold, whilst the 12mm ball gap with wider arms more than doubles stability. I think I was so impressed with the improvement of direct drive over the bowden that I didn't consider the effect of geometry on stability.

            @adrian52 As always, great idea!
            And as usual - we are waiting for the addition to "thingiverse".

                @adrian52 Thank you so much for sharing your ideas with us.
                Do you do any additional fine-tuning in the firmware?

                        @Fred-Y I have been thinking of that solution for my Orbiter 2.0. With my 80mm rod spacing adapter the Orbiter can be mounted horizontally.

                          Made some mounts for the Orbiter 2.0. Works great with my 80mm smart effector adapter. Weight is 12 grams.
