Baby-Door ramp (pet, dog, cat door)

i've found this cool design dog (baby) gate, ramp
by aTypicalEngineer808 (https://www.thingiverse.com/thing:3821442) and was triggered:

we were in need of such ramp because of two cats.
but i've thoght, the ramp was wider than neccessary.
also it was a great opportunity to practice some fusion360. learned a lot in the process!

features:
* modular ramp for baby-doors (and for whatever reason you're using them)
* door can be placed angeld in the door frame, so it closes itself due grav
