Rolling Supports

I liked the rolling supports, they reduce wobble. However, they were mounted to the pedal 2020 profiles, so they moved a circle pad, but tacked straight, so did not run smoothly. These are mounted to the LONG 2020 profiles and move in a circle and they roll perfectly along a circular path. Support is designed with a standard bearing and use the bearing stl from the original to mount on a M4 bolt and lock with an M4 nut.

Use 4 of them, or if you want to minimize, use only 2.

The bumpers keep the max rudder movement more strictly then the one mounted on the middle bar does. Mount on the wooden board with a 3mm wood screws.
