A how-to for making snowflakes for 3D carving or laser cutting using the snowflake generator written by Windell Oskay and ported to the web by Paul Kaplan: http://blog.inventables.com/2014/11/snowflake-generator.html
Alrighty, firstly you need to play with this snowflake generator and make yourself a pretty design: http://blog.inventables.com/2014/11/snowflake-generator.html
When it’s looking real nice-like, save out an .svg.
Import into Easel
Open up Easel (or whatever software you’re using) and import the .svg you just created. Add a hole for hanging it if you please, and resize/rotate until you’re happy.
Send it to the machine and let it rip! Repeat endlessly or variably until you’ve had your fill of the holiday spirit.
