Looking forward to this mod, looks really well thought out.
I had a question about material will be used as well. What is the durability of a 3-D printed ramp? My concern would be strength around the scoop kickout and the posts around the ramp entrance and scoop.
For the ramp flap screws, would it be possible to countersink the holes and use a flathead screw that won't impact the ball's trajectory?
