Cryptex fountain pen case

prusaprinters

<p>Project in nominal scale (100%) was created for 0.2 nozzle or SLA print.</p><p>There is cryptex style combination lock - there are 4 digits but only 5 values for each positions. It's too small to handle all 10 digits and I want it to be <strong>usable</strong> (I just need a case for my pen).</p><p>You have to print:</p><ul><li>bottom:<ul><li>1x Pen_Cryptex_A1,</li><li>1x Pen_Cryptex_A2,</li></ul></li><li>top:<ul><li>1x Pen_Cryptex_B1,</li><li>2x Pen_Cryptex_B2,</li></ul></li><li>combination rings:<ul><li>4x (Pen_Cryptex_C). Print rings upside-down!</li></ul></li></ul><p>Print without supports!</p><p>Print orientation - look at attached screen from slicer.</p><p>Material - I have used PLA (DevilDesign PLA Marble Dark; see photos) but it doesn't matter.</p><p>Assembling:</p><ul><li>glue <strong>Pen_Cryptex_A1</strong> with <strong>Pen_Cryptex_A2</strong>; notice that inside there are small tabs!</li><li>glue <strong>Pen_Cryptex_B1</strong> with both <strong>Pen_Cryptex_B2</strong>.</li><li>next you can put on combination rings (in the same way you can change combination).</li></ul><p>That's all. Look for images - there is simple assembling scheme.</p><p>&nbsp;</p><p>Lock works correctly only when there is pen inside. If you want to use it with something other, there have to be cylinder with size of pen (especially diameter).</p><p>Kaweco Liliput has 96.8mm length (both ends are rounded) and diameter 9.9mm.</p>
