Decided to revisit my MSFFB2 X55 Franken stick.
First image shows the new part I printed on the right, and the original part on the left.
This enabled mounting the X55 handle much lower, closer to where the original MSFFB2 handle sat.
Second image is the part mounted in the gimbal, third image is the X55 circuit board mounted inside the MSFFB2 case, and the wires connected to it (10 enemy teensy wires to be soldered!).
Final image is it all lit up, and you can just make out the X55 USB cable exiting the MSFFB2 base
Now back to the collective project, now I have found the ideal material (nylon as it is very strong, self lubricating, and very light).
