Maker Space 307 Calipers

prusaprinters

<p>These are simple 100 mm calipers I designed for a class I am teaching at my local Maker Space (<a href="http://www.makerspace307.org/">http://www.MakerSpace307.org</a>).</p><p>The calipers are made using both 3D printing and laser cutting. These calipers are very inexpensive. The total cost per caliper is less than $1.00. Currently, they are only capable of outside measurements and only have a millimeter scale.</p><p>I made the caliper body with Inkscape and the amazing "Scale Generator" extension. <a href="http://wiki.inkscape.org/wiki/index.php/Extension_repository#Scale_Generator">http://wiki.inkscape.org/wiki/index.php/Extension_repository#Scale_Generator</a></p><p>Instructions</p><p>&nbsp;</p><p>Materials Needed:</p><ul><li>3 mm Acrylic</li><li>PLA Filament</li><li>#6 wood screw</li></ul><p>Cut the SVG from the 3mm Acrylic. I used the following settings on our Full Spectrum 45W laser</p><ul><li>Vector Engrave (RED) 100 Speed 10 Power</li><li>Vector Cut (BLACK) 10 Speed 100 Power</li></ul><p>3D Print the slide, the settings I used were with 0.3 mm layer height and 15% infill. I designed the file for PLA, so you might have to adjust it if you use another material.</p><p>Once you have the main body cut and the slide 3D printed, you will need to take the #6 screw and install it in the smaller hole in the acrylic. If your screw sticks through the material, just use a pair of pliers, cut the screw, and file it, so it is smooth. Alternatively, you could use a machine screw and nut to accomplish the same thing.</p><p>&nbsp;</p>
