Case for PrusaMini default USB-flash-drive

prusaprinters

<p>Are you also tired of guessing which side of the USB stick has to go which way into the printer? Here is the solution: a housing for you default PrusaMini USB flash drive.</p><p>The fun thing is, you might test some new technics: <strong>printing with 2 different materials </strong>and <strong>inserting parts while printing</strong>. The 3mf files should be ready to go and will contain color change breakpoints as well as the halting-point for inserting the flash drive.</p><p>There are 3 different variants:</p><ul><li><i>usb-case-2color.3mf</i> is the <strong>recommended (savest) version</strong><br>Tested - will work.</li><li><i>with-top-ATTENTION-will-crash-nozzle-into-usb.3mf</i> (maker) version<br>The back side of the flash drive is also covered, which makes the print enclose the flash drive better.<br>Tested - <strong>will work, but will slightly crash the nozzle on 3-4 layers into already placed flash-drive.</strong> Had no problem on my printer afterwards, but<strong> you should be aware of this!</strong></li><li><i>usb-case-standing.3mf</i> is an untested variant. Will only be printed in one color.<br>Should be printing fine - let me know in the comments if it worked. I run out of flash-drives before i could test :)</li></ul><p><strong>How i printed:</strong></p><ul><li>Although the 3mf files are using 0.4mm nozzle i printed with 0.6mm nozzle. Which worked with no problems. If you print with 0.4mm nozzle let me know if you had problems.</li><li>I used PETG - but PLA should work fine. Maybe use a Brim to make sure it is attached properly on the print-surface.</li><li>In the 3mf files there are <strong>print stops</strong> to insert the usb-device in print, and print stops for changing filament at the bottom and the top of the print.</li><li>Before inserting the USB flash drive <strong>i use some glue-stick</strong> on the top and bottom of the drive to get better adhesion of the printed filament.</li><li>After color changes: make sure no remaining strain of filament is above the printed piece, to get a clean print.</li><li>Use a cutter-knife to clean remaining hard edges after print.</li><li>I customized my prints with characters of my choice :)<br>If you want to customize too, you may use the stl files in the program of you choice (i guess thinkercad will be a good choice to keep it simple). You might also use the blend-file if you are familiar with blender.</li></ul>
