Gravitrax Hyperbolic Funnel

Hi,
I tried the hyperbolic funnel from MK_Design, but noticed certain things:
The funnel requires a lot of support to print and even with the support the result doesn't look so well, at least on the bottom side.
I don't need so much inputs, they only result in requiring the blockers, so that the marbles doesn't got out on the oppisite side.
When getting multiples marbles into the funnel at the same time, it's not very stable.
So here my complete redesign. It only used the hyperbolic curve, anything else is new.
It can be printed completely without support, as it uses two parts which simply can be put together, even glue is not nesessary but possible of course. Printing the two parts in different colors gives a good look.
it is very stable, as you have the central spot for placement, as well as 3 places were you can build small towers below to get a robust stand.
You don't need to close the input on the opposite side, As the inputs are some millimeters higher than the main funnel and thus the marble stays in the funnel even at higher speeds. At very low speeds this funnel doesn't work well, in this case you should prefer the original version from MK_design.
This funnel doesn't allow you to place another tile directly beneath the inputs. This would collide with the funnel. Maybe I create another version of this funnel with 3mm less diameter ...
I recommend printing with adaptive layer height setting from cura.
