Adapter to fit a 25mm raspberry pi case fan into a 30mm fan slot.
The fan side is actually 25.5mm and the outer edge of the fan adapter is 29.5mm to allow a loose friction fit instead of having to screw anything together. There is a 'lip' on one side to prevent the fan from falling out, so mount it with the lip opposite the back wall of wherever the fan will be mounted against.
There is also a cutout in one corner to allow the wires through without having to bend too much or remove from the wire holder in the stock fan body.
I found it easier to just print this adapter than remix the raspberry pi case cover I found (I used this case https://www.thingiverse.com/thing:3724434).
OpenSCAD file included incase you need to build for a different size fan or make any other adjustments.
