Printed the bushings and linkage arms at 10% infill
The body printed at 5% with no problems.
No support needed.
The link arms will probably need sanding to make them smooth enough to pull/push the arms without snagging.
I drilled out all my holes prior to screwing, recommended.
I used 1" screws for front and top, a 1 3/4" screw to go through for the side axle.
Servo screws were locked down with small pieces of plastic with a 1/16th hole, or you can find very small screw/nuts for these.
