Bottles and screw cap
thingiverse
The bottle needs extra support that can be easily broken out with a screwdriver and some needle-nose pliers. I added 10% support at 80 degrees but I think 5% could work just as well. There was a bit of leakage near the bottom which I fixed by carefully applying a soldering iron and some waste material. Maybe higher heat settings would solve this problem, I was using 200 C with 3D Spark filament.
