Basically this:
It just wedges between the FL upper strut brace and the back of the master cylinder and stops the master cylinder moving (or at least reduces the movement). I haven't quite got the spacing correct on mine yet so it needs tweaking, and tbh I wasn't satisfied with my printed version. I used PLA which has the highest compressive strength of any of the domestic printing plastics, but it still flexes too much. I did try redesigning it but it didn't help much and then it interfered with the plastic cover on that side of the rain tray.
I am planning to further refine my design to get the angles right and then I'll send it off to my CNC guy to see what it will cost in aluminium, but I'm curious to see what MarkIII's design looks like and how it works
