NOTE: Skull/Punisher fan guard NOT included, link below!
Update Jan 19: Now with a box! I've ripped apart a cheap usb powerbank and put it all in the bottom box and soldered the adapter directly to the charger with a switch in between.
I've made a slot for the micro-usb charging port..
All the electronics are hot-glued in place and I've just superglued the old holder on top of the box.
Just a simple 80mm fan holder that allows the fan to be adjusted.
Print two of each parts and assemble..
You'll need two m3 bolts, two m3 nuts and some washers...
I use it with a usb to 9v boost converter and a small usb batterypack.
This is the boost converter.
Fan guard is not included, it's not my design.
It's thing number: 757895
But If you are like me, do print some guards and save your fingers...
