<p>This is a remix of the <a href="https://www.prusaprinters.org/prints/5381-raspberry-pi-4-and-buck-converter-mk3s-case">Raspberry Pi 4 and Buck Converter mk3s Case</a> from <a href="https://www.prusaprinters.org/social/3955-thejobbitt/prints">thejobbitt</a> found here on Prusa Printers.<br>I needed some changes e.g. bigger rocker switch / power connector, different dc/dc converter (<a href="https://www.google.com/?q=tinxi%C2%AE%205A%2075W%20DC%20DC%20Step%20down%20Converter">Link</a>), need of a second power connector for a top mounted led strip lamp (<a href="https://www.prusaprinters.org/prints/3267-led-light-bar-prusa-i3-mk2mk3">Link</a>).<br>I also added some more vents and improved the groove and tongue.<br>Step/f3d files included so you can modify to your needs.</p><p>Finally I've printed it.</p><p><strong>Had to change some stuff, like the dc/dc converter didn't fit (forgot to measure a side? dunno), added sacrificial layers for the screw holes (0.2mm thick), adjusted some holes (dc/dc M3 screws, RaspberryPi 4 M2.5) and some other things that were related because of the resize of the whole case.</strong></p><p><strong>UPDATE</strong> <i>May 9th, 2020 03:54 GMT+1</i><br>I've added some pictures from the final "product" :)<br>I may update the files once more.<br>I noticed while I put all together, that one cooling slot near the power connector for the led lamp can be removed and the mounting holes (hex nut) for the dc/dc converter can be a little (0.05 mm in radius) smaller to achieve a tight fit.</p><p>Besides of that, it works great! So don't panic if you already printed one!</p><p>If you have any questions regards the model or the assembly of all, you may ask me. :-)</p><p>P.S.: Yes... one heatsink is rotated by 90°.. Guess I got to excited at this point. ;-)</p><h3>Print instructions</h3><p>Print with 0.2 mm layer height and 10% infill.</p>
