The Chip Flip Clip: Print-flat-and-fold bag clip

prusaprinters

<p>Keep your snacks fresh! A simple, one-piece bag clip that prints flat and uses the initial layer as a living hinge to fold up. The centre oriented clasp locks the clip in-place with a satisfying click. Flip it up to release. The clasp is intentionally short creating a leaf-spring-like tension on the model that really grabs the bag.</p><p>This is a quick print with just a few dozen layers and uses only about 7 grams of filament.&nbsp;</p><h4><strong>Filament</strong></h4><p>Print it in your favourite PLA. Pictured is CC3D Copper PLA, IIID Max Light Blue PLA, and Filament Factory Food Safe PLA Black.</p><h4><strong>Special printing instructions</strong></h4><p>There are two different models included one for 0.2 mm layer height and another for 0.3 mm layer height. <strong>Make sure you set your slicer's layer height to match the model you're using.</strong></p><p>I printed these using a 0.4 mm nozzle with a 0.6 mm line width and flow of 105%. In short, extra flow and wide lines makes a better, more durable living hinge. The 0.3 mm model prints a little faster but some extruder / nozzle / filament combinations may have trouble keeping up with the higher flow. This model relies on tensile strength of the first layer, so if you are using a decorative, lower strength filament, the 0.3 mm layer height will likely be more durable.</p><p>As designed, only the initial layer will form the living hinge. The <strong>initial layer's lines must be perpendicular to the fold</strong> (i.e. they will run parallel to the longest dimension). &nbsp;You can achieve this a few ways.</p><ol><li>In Cura, set the “Top/Bottom Line Directions” to <code>[ 90, -45, 45, 180 ]</code></li><li>If you can't find that setting or use a different slicer, you can rotate the model in your slicer to make sure those lines are running in the correct direction.</li></ol><p>It will end up looking something like this:&nbsp;</p><figure class="image"><img src="https://media.printables.com/media/prints/235080/rich_content/a75e7e57-e3f0-4e54-b3d8-038757263f80/screen-shot-2022-07-02-at-93005-am.png#%7B%22uuid%22%3A%2224a78318-3393-42df-bb31-40423b22872d%22%2C%22w%22%3A1840%2C%22h%22%3A796%7D"></figure><p>&nbsp;</p><p>&nbsp;</p>
