I didn't need DC power, or 20v power, and didn't need to monitor my voltage - I just wanted to have it run from a USB-C cable. I like the looks of this one a lot so decided to be lazy and remix it.
I removed the voltmeter, step down module and DC ports, maintaining the footprint for the USB-C trigger which on mine is 12v to directly power the fan.
I didn't use some of the components as a result of making my changes. As of writing this, the original model has Socket Head M4 55mm x 2, however that was far too long for mine - I'm not sure if it was a typo on the original but find below the parts I used.
The fan I used already had corner braces so I ended up not using the printed parts, but I've kept them aside should I want to upgrade the fan in the future.
This is only for the front of the body, the rest of the files are untouched so please download them from the original model.
The author remixed this model.
