I printed everything at 30% infill except for the bolts, Those I did at 80%.
I think 80% infill is stronger than 100%. (I could be wrong)

All pieces have been uploaded, I will be adding more instructions over the next few days.

Qty 2 -- 625zz 5 x 16 x 5 mm bearings will be needed for the pivot.

To assemble, remove the support arms from the stand assembly arm (thing:3113191).
Bring them both straight up vertical.
Attach the new CG Bracket between the two support arms using the same bolt, nut and knob that was holding the support arms originally.
Attach the new CG Arm to the bracket using a new 1/4” x 1 1/4” Carriage Bolt and Nut along with the newly printed Knob.
Insert the bearing into the CG Rocker with the bearing flush with the side without the line.
Lightly sand the bolt shoulder before trying to insert it through the bearing.
You want a tight fit so you don't have any rock between the bearing and the bolt shoulder.
The bearing should be on the inside and the bolt should be pointing out.
Once the bolt has been inserted into the bearing place the CG Spacer of the bolt, all the way up to the other side of the bearing.
It should stick out slightly beyond the edge of the Rocker.
This is to put space between the Rocker and Arm.
Insert the CG Swing Stop Shaft through the CG Rocker and have it flush on the same side as the bearing.
Now install the CG Rocker on the inside of the CG Arm with the bolt and the Stop Shaft pointing out.
With or without the CG Washer thread on the nut. (Washer is optional)
Tighten fully and then back of a half turn.
You can use some Loctite if you nut is too loose.
The CG Rocker should rock freely.

I am going to add some Neoprene Foam to the edges of the rockers that touch the plane.

I will add some more pictures in a day or two.
