The rain roof is very nice thing but it is sensitive to side winds. The Velcro lets lose then and you have to catch it. With these studs this might improve (still have to test it in windy conditions).The STL already has the 2 studs in the printable orientation. The scad design only has 1 stud so you have to rotate it and for the second stud mirror it around Z so you have a part for the left and the right of the bike.
This version 2 of the design. I hope it holds the rain roof better with side winds.
