Phi Snowflake Generator

Tried out BlocksCAD when I saw the snowflake contest. After a few hours of messing about and trial and error I started to put together a customisable snowflake based on the real world snowflake principle of the fibonacci ratio.
I'm not a coder so it always takes me some time but the visual block method of BlocksCad enabled me to try different things out and go back and try again until things started to go the way I wanted them.
I often have to sit back and grab a pen and paper to try to work out the algorithms but, with a bit of research into the behaviour of real snowflakes, I managed to get something that looks pretty decent when printed out - I suppose it looks better printed because all the imperfections of my printer (a relatively new Anet A8) mimic the real imperfections of the natural world.

Play around with the variables to see what different shapes you can make: most are self explanatory apart from the 'branch_length" one which returns a longer length with a smaller numbe
