Window Bird Feeder

This window Feeder is an improvement on my old design.

same basic design but only using 1 40mm suction cup 

instead of 4 like the previous design 

I have tested it had it for the past 3 month 

and had no problems with only using the one cup

Printed with supports 

can be a pain to remove from the door inserts 

but necessary to make sure the feeders door will insert correctly  

Window feeder with perch and removable food tray for easy refill and cleaning 

Using 1 30mm suction cups that attach to the window 
I made the Perch detachable form easier printing 
Has a large window on the back of the feeder for viewing
