Caravan Door Knob

The knob is fully functional and can be used to open close and lock the door for Adria caravans(might fit for Hobby and other brands as well).
It is more robust as the original handle so you can close the door more smoothly and do not need to slam the door to fully close it.
For the printability of the model, I've split to model into 5 pieces.

 #1-#3 have to be glued together

#1 External ring

#2 Baseplate for locking pin

# 3 Shaft with thread and octet pin holder

#4 Stabilising plate for cover plate

#5 Knob

Print parameter:

#1/#2 Infill 30% Layer-Hight 0.16

#3 infill 100%(stable pattern) Layer-Hight 0.16

#4 Infill 30% Layer-Hight 0.25

#5 Infill 30% Layer-Hight 0.1 or variable layer high

Last picture shows the parameter for the thread if someone wants to design their own knob
