Fixed model issues, cleaned up print and made it faster/easier.
To attach flowers take butane torch/lighter and quickly/lightly heat up end of green filament for stem, then take flower base and press on to melt/fuse together, blow on it to cool and it will fuse in place, repeat on other end to attach flower base, petals, then center, you can alternatively glue together if you're not comfortable with that. With base I'd only do it by quickly fusing/melting stem end and pressing into base as otherwise it's a bigger headache.
lightly torch flowers once mounted to give them realistic curls (practice on a couple flowers first to get them where you want them).
