I finally got back over to TechShop this evening, for another laser class. And I really need to get in habit of taking pictures — forgot again tonight.
Anyway, we learned how to put a special attachment into the lasercutter, which supports a cylindrical object, and spins it as it etches. Our sample project was just etching some letters onto a beer bottle, but I can see a lot of potential for interesting projects.
Next up is refining my salt and pepper. I may learn to vacuum form, and try to form the parts that way.
