Sliding roof system 1

The system includes three roofs: a gray fixed roof, beige and yellow mobile roofs. The yellow roof slides on a blue fixed runway. The beige roof slides on the blue fixed runway and on the runway made on the yellow roof. The yellow roof is driven by the brown motor via red chain drives. The yellow roof is attached to the upper branch of the chains. The beige roof is driven by the pink part fixed to the yellow roof. The pink part fixed to the beige roof restricts the movement of the beige roof. STEP files of this video: https://www.mediafire.com/file/8dx45k...
