MT3608 Micro USB DC-DC boost case

<p>This is a case for the 2A Micro USB boost converters found all over <a href="https://www.aliexpress.com/item/DC-DC-Adjustable-Boost-Module-2A-Boost-Plate-2A-Step-Up-Module-with-MICRO-USB-2V/32741127985.html">AliExpress</a>. The chip used is an MT3608 but the chip is marked as "B6286 (K)"</p><p>I use mine to test my 12v projects from a 5v USB powerbank instead of firing up the bench supply. As they can go up to 28v I thought I'd make a case for it.</p><p>There's a hole on the side for screwdriver access to the potentiometer. You could perhaps make the case 1-2mm narrower and have the pot sticking out the side.</p><p>Round corners for nice printing and press-on lid that requires no glue.</p><p>I've printed using FlashPrint in PLA with 0.30mm/15% infill and also 0.18mm/100% infill for more rigidity and it looks smoother.</p><p>Don't bother with supports, the holes are so small its actually better without supports which can make the edges look messy when removed.</p>
