Quick update for anyone interested...
I've just printed a replacement steering shaft for the controllers, from Graeme's ZIP file. I printed it on my K8200 3D printer using 3mm PLA, I ended up printing it with the stop part at the bottom and using supports.
the print took about 3 minutes to complete, it then took an hour or so to file away the excess so it fitted!... But it does and I now have a working controller again.
