We're working on the final revision.

Assemble your FRS unit. If you are using printed parts for the housing and cover, ensure that they fit together well.

Be sure the bearing rotates freely without interference from any printed protrusions.

Be sure the filament guide protrusions fit together well and provide a clear filament path free of obstructions.

DO NOT drop the ball bearing. (you will never find it again)

When everything is good, do your final assembly with two screws.
