class=\"wp-caption-text\">Ruler and Tool Bag provided with the Lulzbot printer<\/p><\/div>\n<p>The Lulzbot printer comes with a variety of tools in a nice little tool bag, and one of the items is a 150mm ruler.\u00a0 It&#8217;s sufficient for short measurements where accuracy isn&#8217;t a major factor, but for the rather precise parts and fittings I&#8217;m building, I needed something a little more accurate.<!--more--><\/p>\n<p>While wandering around the Phoenix Fry&#8217;s Electronics store, I found (after asking the very helpful staff there) two electronic models from General Tools &amp; Instruments.\u00a0 I ended up buying the larger <a title=\"General Tools Model 147 at Fry's Electronics\" href=\"http:\/\/www.frys.com\/product\/5270947\" target=\"_blank\">Model 147<\/a> for just under $40.\u00a0 I read some reviews of this and similar models on the Amazon site, and a number of people berated the accuracy and battery life.\u00a0 But in my opinion, it works extremely well for my purposes.<\/p>\n<p>It will read in millimeters, which is very useful when designing in FreeCAD.\u00a0 And if you <strong>want<\/strong> to go to inches, it&#8217;ll do both decimal and fractional inch measurements.<\/p>\n<p>To alleviate the battery life problems, my model automatically shuts off after a few minutes.\u00a0 All you have to remember is to close the caliper all the way before turning back on, or hit the &#8220;zero&#8221; button after closing it.<\/p>\n<p>This is the six inch version; they have a three inch version for about half the price.<\/p>\n<div id=\"attachment_81\"
