rotary funnel for fischertechnik Marble run

Rotary funnel for fischertechnik to print yourself.
The first fischertechnik Marble run kits are without funnels. The new kits each contain a funnel.
The design I changed so that the funnel is easily printable.

I have deposited the following models:

- 90mm radius 12 degrees tilt 15mm height easy
- 90mm radius 12 degrees inclination 15mm height with groove for rail
- 120mm radius 16.5 degrees tilt 30mm height with groove for rail


Have fun with the great kits from fischertechnik.
