Custom Delrin Fixture for Milling Four Dog Tags at Once

Posted by Goli Mohammadi on Sep 12, 2018 1:03:25 PM

Bantam Tools community member Roberto Lo Giacco, who’s based in Rome, Italy, recently shared a neat custom fixture he milled with and for his versatile Bantam Tools Desktop PCB Milling Machine. Milled out of Delrin, one of the best performing engineering plastics, the fixture firmly holds four aluminum dog tags at once. He also wrote up his R&D process and shared all his design files on his site

Roberto and his friends are working on a project for the upcoming massive Maker Faire Rome event taking place in October. The project requires them to mill a couple hundred dog tags. While the reliable Bantam Tools Desktop PCB Milling Machine can handle that with ease, fixturing one at a time would be quite time consuming. Roberto just made the task four times faster with a little ingenuity.
