Cordless Fume Extractor

There's a narrow duct running up the right side assembly that conceals fan wires while allowing the fan to pivot freely. The fan I used has extremely thin wires, making it easy to push two of the three necessary wires into place without any issues. However, if your fan features thicker wires, you may need to consider this factor before proceeding. The on/off switch note is worth mentioning since the 3D model doesn't have a hole for it due to my use of a large switch. You can drill and install your own size switch after printing. The fan fits snugly inside the case, so I didn't bother screwing it down - although holes are provided (3mm) if you prefer to do so. You can glue the main body onto the tabs provided by the side assemblies, but mine fit very tightly, eliminating the need for this step. I left an opening at the bottom to enable adjustment of the boost converter as well as replacement of the 18650 battery if necessary. The battery holder features a built-in charger and regulator, and I used the 5v output.
