Hape Quadrilla unique Block

My boy got a marbel run that that consists of individual parts.
This way you can build your own runs, in our case with soundeffects as well.
But one of the track from the manual showed a little flaw in the designe. One of the Parts, where marbels can go trough horizontal and vertical, was used in a way that some marbels will repeatedly fall of the track.

Long Story short:
Here is the Part which is a identical copy of the original except that the horizontal hole does not go trough the entire block.

Fits perfectly with the original Parts of the Toy.

Print instructions

I printet it upright so most of the surfaces look the same and have this uniform feeling.
However, you will need to print it with supporting the inner ring which isn't laying on the Bed.
Printet it with some generic green PLA with 25% infill. Not for stability but for the extra weight.
