CLICK pen

prusaprinters

<p>About a year ago, I thought it would be nice to create a 3D printable pen model with a <strong>real retractable click mechanism</strong>, as developed by Parker company in 1965. Today there is probably no one who would not use it.<br>I wanted to:<br>1/ make it completely 3D printable (except for the pen refill and the spring).<br>2/ use 0,2mm layer height.<br>3/ eliminate any post processing.<br>4/ allow easy assembly.<br>5/ make it work !!!</p><p>In the end everything worked out and I was very happy about it. All components are 3D printable (barrel, tip, plunger and cam) and work together properly. For now I made 2 simple cylindrical versions, <strong>with clip and without it</strong>.<br>I was wondering how to share it with others but when the PrusaPrinters came up with this contest, there was nothing to deal with.<br>So I am really honored to welcome this clever mechanism to the world of 3D printing.</p><p>Tested refills, often used:<br>1/ large capacity G2 refill (length 98mm)<br>2/ simple narrow (length 107mm)</p><p>Printing:<br>Please see 3mf file. Everything you see in it has it's own reason (especially printing orientation). I use brim to print everything for sure, but maybe it's not necessary.<br>All testing was performed using PLA.</p><p>Assembly: &nbsp;</p><figure class="media"><oembed url="https://youtu.be/8p4-5Gi62YA"></oembed></figure><p><br>1/ peel off brim</p><p>2/ clean a bit edges and <strong>tips of plunger</strong> (just with fingernail)</p><p>3/ insert plunger and cam all the way down into the barrel</p><p>4/ insert pen refill with spring into the pen tip</p><p>5/ screw pen tip with barrel together (for the first time the thread is tight)</p><p>6/ during the first clicks, the parts grind a little and then you're done ;)</p><p>&nbsp;</p><p>Also please check out:</p><p><a href="https://www.youtube.com/channel/UChKp-968z1i5PN29gbR7YfA">https://www.youtube.com/channel/UChKp-968z1i5PN29gbR7YfA</a></p><p><a href="https://www.cgtrader.com/rorys3d">https://www.cgtrader.com/rorys3d</a></p><p>&nbsp;</p>
