Parallel Bars for Milling Machine or Other Process

Some parallel bars I printed for the metal shop guys at work.  Faster for me to do this than for them to make a set for sure.  That and they're consumable as well, so if they ever need more I just click print.  Can change the amount of top/bottom layers for a more accurate size across the width if you like.  We aren't quite making rocket ships here, somewhat sorta similar but not quite a rocket ship lol.  

Feel free to use these in your shop at home or at work :) Any issues let me know and we'll figure it out:)
