The file 'Remix Paddle For Bowls Of Joy Model Marble Run By SNOWGHOST235 3D Printer Model' is (stl) file type, size is 88.7KB.
I was scrolling through Thingiverse searching for the perfect marble run when I found the Bowls of Joy Marble Run by SNOWGHOST235. I saw that it's a coaster in the 1910's that uses a "paddle" to accelerate cars up to 51km/h/30mph, which made me fell into that choice.
However, I noticed that the paddle doesn't carry marbles from the bottom and the top. The middle works fine and I used a 12.6mm ball bearing (from my Gravitrax)
So I cut out a part from the paddle and the top works better, except the bottom. So I made my remix of the paddle with something extra that improves the design.
Note that this is a Work-In-Progress, I have not been able to print it now!
