The file 'Gravitrax Drop Slide 140mm Height 3D Printer Model' is (f3d,stl) file type, size is 330.3KB.
The normal drop rail from Ravensburger only drops a maximum of 75mm, but the slide shown above drops at 140mm! If you are having trouble using the one-time rubber band cannon (https://www.thingiverse.com/thing:4800097) that doesn't allow multiple marbles to go without resetting it, that model is perfect for you if you don't want to spend money on the fast drop rail from the Shetland3D Etsy shop even though you still have your 3D printer with you. Plus, @MaskedMarble had a batch from the Shetland3D Etsy shop and said that the print quality is on the poor side for some reasons.
You can also use https://www.thingiverse.com/thing:5576205 to also get the part working even with multiple marbles, perfect for using it as a infinity loop.
Print two of the rings per slide (one should also work, but it doesn't look that good).
Ring is taken from: https://www.thingiverse.com/thing:4900813
If you make this, it would be awesome to see pics of your makes!
