Bird Feeder

This is a feeder mainly for wood pigeons which like to feed amongst the flower beds. The bottle should be thin enough at the neck (like the one i used) for the pigeons to get their heads in to eat. It is intended to be used in standing position that can be easily taken inside during bad weather, to be refilled or at night (the slugs love bird food).
I have added a top to protect from light rain showers. It is in 2 parts. The part that grips the top of the 1 litre bottle can be used on its own. (The 1 litre bottle must measure 78mm across.. scale x and y if it is not).
The roof that is glued to the grip is more cosmetic and for those that like a challenge.
The roof is hollow and requires (everywhere) supports to print properly.. (and scaled if the grip part was scaled)

I used PLA, for food safety and prototyping.. PETG would probably be better though for use in the sun and longevity. No supports are required.
The important settings i have used for the roof part (only) are :
support pattern -- Lines
Support Placement -- Everywhere
Support Line Count -- 1
Connect Supports
Support Line Distance -- 2.8
Support x y Distance -- 0
No Support interface
Support Top Distance -- 0
Support Bottom Distance -- 0
