Step 3: Vectorise the Design
You will need to check the file settings for the laser cutting service you are using. This product was made by me ( HiTech Antics ) but I only service Australia, if you are in the United States you could use Ponoko or Pololu Each company will have a specific set of rules to set cutting and engraving.
Before going any further, review your design. Visualise the assembly in your mind. Try and make sure that there isn't anything you have forgotten or overlooked. If possible, print the design out 1:1 and cut out each piece, this will give you a good feel for the scale and other things that can't be achieved by staring at the screen. It is also a good time to fill up your sheet with other nick-nacks (like keyrings or jewelry), I added a zombie head, just because!
