This solution is part of my Lesson entitled, Elementary TT: Challenge 38 Step-by-Step which s in the Education section.



Nice work!
Collecting the hints from solutions by other people here, you may easily reduce the number of parts needed from 27 to 24:

  1. Shift the diagonal of steering bits one step down and to the left: saves two ramps (replacing three, one needed on top).
  2. You may remove the rightmost and lowest ramp by turning the one that is above and left of it to the left.
