I am fairly new to 3D printing... I had to change a few thigns t omake it work, but I got it. This is my first big print :-)
Had to add two connections on clutch area and block to improve bridging. Printed at 200% scale as i got no movemnet at 100% (not enough clearance). Had to add special supports under connection rods to stabilize them during printing. Added two small connections between connection rods mid way up for further stability.
