Birdfeeder Soda Stream Bottle

I remixed, and combined to sodastream bottle bird feeder.I used the “old” sodastream PET bottles which don't fit my new SodaStream anymore.The Roofsegment part has to be printed upgright with support (like on the last picture)6 roofsegments have to be glued on the support ring, and this support ring should be screwed on the bottle
