<p>Extended version of original "Fully parametric spice rack" by Reven.&nbsp;</p><p>Against original (https://www.prusaprinters.org/prints/44067-fully-parametric-spice-rack) you can define different widths and heights for each drawer.</p><p>For example you can have:</p><ul><li>Drawer on the left 100mm width &amp; 30 mm height</li><li>Drawer on the right 50 mm &amp; 70 mm height</li></ul><p>You can control width and height trough variables:</p><pre><code class="language-plaintext">Tw = [105, 40, 80, 20]; // tray width Th = [80, 50, 80, 50]; // tray height</code></pre><p>Where values are related to drawers from the left (on example: 1st drawer 105 mm width &amp; 80 mm height, 2nd drawer 40 mm width &amp; 50 mm height, etc.).</p><p>I didn't do comprehensive testing so in case you'll discover bug, feel free to put it into comments :).</p><p>&nbsp;</p><p><strong>Assembly</strong></p><p>I hit the issue, that I needed bigger drawers than there is my printing area, thou I tested it's possible to make it working :)</p><p><strong>Assembly - Drawers</strong></p><p>Drawers can be printed as multiple prints, thou you probably need to adjust tolerances to be more lose as you will not manage to stick parts together perfectly.</p><p>Lose tolerances:</p><blockquote><p>To = 1;&nbsp;<br>Ts = 0.4;<br>Tg = 0.1;</p></blockquote><p>Note, that rails are not going through whole drawer =&gt; if you cut drawer behind the rails, you can use standard tolerances.</p><p>&nbsp;</p><p>For putting drawer PETG parts together I used Revell's glue and it's holding surprisingly strongly even with quite high load.</p><p><strong>Assembly - Structure</strong></p><p>You can print each part individually, thou problem is to stick them together. Glue will not work in this case, areas are not big enough to create stable connection as I found out hard way.</p><p>What worked for me is solder pen. I put it to 250 degress and just slide through each connection point once (the gap between each part). It melted both pieces together and created very strong connection.</p><p><strong>Assembly - Structure thickness</strong></p><p>I printed my structure with thickness 2.1 mm. Which resulted in quite floppy structure. It's definitely not sturdy enough if structure stands without additional support =&gt; I added double sided duck tape from 3M on bottom and right pillars to glue it to cabinet which made it very stable and nicely working even when operating with drawers.</p><p>My recommendation on thickness would be:</p><ul><li>Use 2.1 or more if you plan to glue it on bottom and side to something.</li><li>Use at least 3 mm if you plan to operate it without additional support (not tested, just gut feeling that 3 mm will be total minimum).</li></ul><p>&nbsp;</p>
