I made it at Techshophttp://techshop.ws
Last week I learned to use the rotary attachment
for the Trotec Laser. Usually this attachment is used to etch cylindrical and conical objects like glasses and bottles. I wanted to try something different, something... spherical. Also, I wanted to etch some leather. Putting two and two together, I decided to etch a baseball.
I'm not really crazy about the design on this ball - it was sort of a 2nd draft to work out the kinks in the process - but I thought I'd take a break and get this Instructable written.
I've attached the template i used for my design as a PDF.
