<p>I wanted a spool holder that clip on the spool and use as less space as possible because I will put my spools on a threaded rod over the printer in my rack-mount, so I can put 5 spools in one bar!</p> <p>Also this spool holder use a standard ball bearing, so it turn very smoothly.</p> <p>The STL file work with a standard skateboard ball bearing (22mm x 7mm), inside spool diameter of 56.5mm and tickness of 6mm.</p> <p>SCAD file is included so you can set your spool size, see instruction.</p> <p>UPDATED 2014-12-17:</p> <p>With the suggestion of sgraber, I added 2 new variables to remove the locking ring and disable the hole to save PLA.</p> <p>Also now the hole to save PLA will work with smaller diameter of any size.</p> <p>UPDATED 2014-12-19:</p> <p>Youtube video added: <a href="https://www.youtube.com/watch?v=p5wZdxiFyGA">https://www.youtube.com/watch?v=p5wZdxiFyGA</a></p> <p>UPDATED 2014-12-20:</p> <p>Updated SCAD script, I changed some variable name (bug from find & replace) and corrected a bug with the spool tickness.</p> <p>Also I added a new STL with different dimension, I use both of this configuration.</p> <p>UPDATED 2014-12-21:</p> <p>New youTube video added with more spools <a href="https://www.youtube.com/watch?v=lng9eZjR9RE&list=UUg0rSjryYrw6MFuhJREnz4w">https://www.youtube.com/watch?v=lng9eZjR9RE&list=UUg0rSjryYrw6MFuhJREnz4w</a></p> <p>UPDATED 2015-01-03:</p> <p>Updated SCAD to support better bigger ball bearing size and bigger spool diameter</p> <h3>Instructions</h3> <ol> <li>Customize the openscad script for the desired spool dimension</li> </ol> <p>The only thing you need to set is the spool_inside_diameter and spool_tickness so that your spool holder fit correctly on your spool.</p> <p>Once set, save and build the model, once build, export the STL file on your printer.</p> <ol> <li>Print the spool holder without support material.</li> <li>Install the skateboard ball bearing (22mmx7mm)</li> </ol> Category: 3D Printer Parts
