I live in Cleveland, Ohio, which has a fantastic library system - 3rd-biggest public library in the nation! 
 
 The "TechCentral" section in the basement has a free laser cutter - awesome stuff! I made a template for a bunch of markers based off of this print-friendly template.

 Both 
etching AND 
cutting them took about 1 hour and 20 minutes; so a bit longer than I had hoped.
 
 
 
 They turned out swimmingly!

 More than enough for two people.
