Robust BUCKLES

prusaprinters

<p>The goal was to create a buckle design that is <strong>durable</strong> and of course adapted to 3d printing.</p><p>It often happens that the buckle (e.g. on a backpack) breaks when you step on it. I believe that these 3d printed buckles will last, since they are <strong>basically two plates</strong> that fit together. For latches I'm using a compliant levers integrated and better protected in the printed part.</p><p><strong>Update (19/10/2022)</strong>: Tuned clearance of mating surfaces for better sliding of parts. All parts except the pins are new.</p><p><strong>Update (15/11/2022)</strong>: Added 2 new widths, 41mm and 46mm. Added .stp files for F21 and M21.</p><p><strong>Here is a short video introduction:</strong></p><figure class="image image_resized" style="width:58.42%;"><img src="https://media.printables.com/media/prints/281536/rich_content/3aac1bda-fa06-4c95-8bab-277ce7272351/20220925_215413_1.gif#%7B%22uuid%22%3A%2245791d86-f6e4-4874-a9bc-99b23494717e%22%2C%22w%22%3A656%2C%22h%22%3A368%7D"></figure><figure class="media"><oembed url="https://youtu.be/hQz46N0zUtA"></oembed></figure><p>&nbsp;</p><p><strong>Variants:</strong></p><p>The BUCKLEs comes in 7 widths of the slot for strap (<strong>21mm, 26mm, 31mm, 38mm, 41mm, 46mm and 51mm</strong>).</p><p>&nbsp;</p><p>Every width comes in 2 variants.
