this is a print in place flex bridge that cover two tiles span.
the base plate is base on the six exit base plate by alex80it (https://www.thingiverse.com/thing:3552100)

because of the design's tolerance, the slope is 3 cm, the receiving platform need to be 3cm lower.
try different speed for the ball to move the bridge down and roll down, too fast will bounce back from the bridge, too slow will not make it roll.

print in PLA works perfect, petg doesn't work

I added 2 insets, one 120 degree fast curve, and one straight one with a bump, so when the ball bounce it has more chance to move back to the slope.
