Parametric SD Card Wallets

prusaprinters

<p>An OpenSCAD implementation of parametric SD Card wallets, designed with 3D printing in mind. I got inspired to design this after seeing, printing and liking Natalucciu's <a href="https://www.thingiverse.com/thing:2995302">SD Card Wallet</a>. I liked it so much that I had to improve upon it to my liking :), by making it <strong>as small/compact as possible</strong>, adding a <strong>wallet close lock</strong> and making <strong>several wallet configurations</strong>. Although inspired by Natalucciu's project, my project was made entirely from the ground up, all files are original.</p><p>Need to hold some Micro SD Cards too? Use a Micro SD Card to SD Card adapter or print this one here (I have not yet tested it myself): <a href="https://www.thingiverse.com/thing:3520171">https://www.thingiverse.com/thing:3520171</a></p><p>I exercised the lock mechanism more than 160 times on one of the prints, without any loss of functionality. The spring will give a little on the first usage but that's OK, it is expected.</p><p>The output STL files for a few practical configurations are included, ready to be sliced and printed: for 1x1 (2 cards), 1x2 (4 cards), 2x1 (4 cards), 2x2 (8 cards), 3x1 (6 cards), 3x2 (12 cards) and 3x3 (18 cards) wallets, but you can find the design files and more information on making your own in my GitHub repository: <a href="https://github.com/nunojay/PrintableSDCardWallets">https://github.com/nunojay/PrintableSDCardWallets</a></p><p>I can add STL files for more configurations if you like. Any feedback is appreciated.</p><p>Enjoy :)</p><p>&nbsp;</p><h3>Print Settings</h3><p><strong>Printer Brand: </strong>Creality</p><p><strong>Printer: </strong>Ender 3 Pro</p><p><strong>Rafts: </strong>No</p><p><strong>Supports: </strong>No</p><p><strong>Resolution: </strong>0.20</p><p><strong>Infill: </strong>30%</p><p><strong>Filament: </strong>Tucab Fil3D PLA 4032D Black/White&nbsp;<br>&nbsp;</p><p><strong>Notes:&nbsp;</strong></p><p>Printing should be done with 0.2mm or better layer height, no supports. Printing parameters depends a lot on your slicer, printer and filament. In my tests I have used Ultimakercura 4.6.2, Creality Ender 3 Pro and Tucab's Fil3D PLA 4032D Black filament ("regular" PLA; <a href="https://mauser.pt/catalog/product\_info.php?products\_id=096-8758">https://mauser.pt/catalog/product_info.php?products_id=096-8758</a> ) and INZEA White (harder to break on bend and a bit easier to print; <a href="https://mauser.pt/catalog/product\_info.php?products\_id=096-8511">https://mauser.pt/catalog/product_info.php?products_id=096-8511</a> ). I manually optimized Cura settings for a much smaller printing time than the default Cura settings for my printer (Standard Quality 0.2mm), but it should print just fine on the default Standard Quality. You can find my Ultimakercura profile in the files (for Tucab's Fil3D PLA 4032D black filament).</p><h3>Post-Printing</h3><p>The wallets are printed already assembled. Upon removal from the printer's bed, hold it with fingers near / on each hinge and force it slowly to close until it breaks loose and the hinge starts working. The SD Card springs also need to be gently pushed at the tip until they get free from ground.</p><p>&nbsp;</p><p>Category: Gadgets</p>
